Explanation chief in your Level:

At the A1 level, the word 'chief' is most easily understood as another word for a 'boss' or a 'leader.' Imagine a group of people working together; the chief is the person in charge. You might see this word in simple stories about tribes or in titles like 'Police Chief.' As an adjective, it means 'the most important.' For example, if you have three reasons for liking a toy, your 'chief reason' is the one you like the most. It is a good word to know because it helps you talk about who is the leader in a group. You should remember that it sounds like 'cheef' and rhymes with 'leaf.' Even though it is a B1 word, A1 learners can use it in simple sentences like 'He is the chief of the village' or 'My chief friend is Sam.' Just remember that the chief is always the top person. If you are playing a game, the person who decides the rules could be called the chief. It is a very strong word that shows someone has a lot of power. When you see it in a book, look at the picture to see who is leading the others; that person is likely the chief. You don't need to use it often at this level, but knowing it will help you understand stories about heroes and leaders. Always remember that a chief is a person, but 'chief' can also describe a thing that is very important. For example, 'The chief food in my country is rice.' This means rice is the most common and important food. It is a simple way to show that one thing is more important than others.

For A2 learners, 'chief' becomes more useful as you start to describe people's jobs and the importance of different things. You will often see it in the news or in stories about the community. A 'Police Chief' or a 'Fire Chief' are common examples you might hear. These are the people who lead the police and the fire fighters. As an adjective, 'chief' helps you prioritize. Instead of just saying 'important,' you can say 'chief' to show that something is the *most* important. For example, 'The chief problem with my car is the engine.' This tells the listener that while the car might have small problems like a broken radio, the engine is the biggest and most important problem. You should also be careful not to confuse 'chief' with 'chef.' A chef cooks in a restaurant, but a chief leads a group. They sound different too! 'Chief' has a 'ch' sound like 'cheese,' and 'chef' has a 'sh' sound like 'shop.' At the A2 level, you can start using 'chief' in your writing to make it sound more professional. Instead of saying 'The main reason I am late is the bus,' you could say 'The chief reason for my delay was the bus.' This sounds a bit more formal and clear. You will also find 'chief' in compound words like 'Chief Executive Officer' (CEO), which is the top boss of a company. Knowing this word helps you understand how businesses and governments are organized. It is a word about hierarchy—who is at the top and what is at the center of an issue.

At the B1 level, you are expected to understand and use 'chief' in both its noun and adjective forms with confidence. As a noun, it refers to the head of an organization or a specific department. You should be familiar with titles like 'Chief of Staff' or 'Chief Editor.' These roles imply significant responsibility and leadership. As an adjective, 'chief' is used to identify the primary or most significant element in a set. For instance, in an essay about climate change, you might write, 'The chief cause of global warming is the burning of fossil fuels.' This usage is very common in academic and professional English. You should also be aware of the adverb 'chiefly,' which means 'mostly' or 'mainly.' For example, 'The residents are chiefly concerned about the new construction.' Understanding the difference between the adjective 'chief' and the adverb 'chiefly' is a key milestone at this level. You should also start to notice that 'chief' is rarely used after the verb 'to be.' You wouldn't usually say 'The reason is chief'; instead, you would say 'The chief reason is...' This is a subtle grammatical point that helps your English sound more natural. Furthermore, you should be aware of the cultural contexts of the word. While it is a common professional title, it also has historical and cultural significance in Indigenous communities. Using it respectfully and accurately is important. At B1, you can use 'chief' to add variety to your vocabulary, moving beyond simpler words like 'main' or 'boss' to express more precise ideas about leadership and importance.

At the B2 level, you should be able to use 'chief' to navigate complex discussions about hierarchy, importance, and organizational structure. You will encounter the word frequently in business journalism, legal documents, and academic texts. As an adjective, 'chief' is often used in the phrase 'chief among which' or 'chief among these,' which is a sophisticated way to introduce the most important item in a list. For example, 'There are many reasons for the company's success, chief among which is its innovative marketing strategy.' This level of usage shows a high command of English syntax. You should also be comfortable with the many 'C-level' executive titles, such as CEO, CFO, COO, and CTO, and understand the specific responsibilities each role entails. In terms of synonyms, you should be able to distinguish between 'chief,' 'principal,' 'primary,' and 'foremost.' While they are often interchangeable, 'chief' often carries a stronger sense of official rank or status. You should also be aware of the word's use in fixed expressions and idioms, such as 'Commander-in-Chief' or 'Chief Justice.' These are not just descriptions but formal titles with specific legal and political meanings. At B2, your pronunciation should be clear, and you should never confuse 'chief' with 'chef.' You should also be able to identify when 'chief' is being used informally as a term of address and understand the potential social implications of using it that way. Overall, 'chief' at this level is a tool for precision, allowing you to clearly rank ideas and individuals within a complex narrative or argument.

For C1 learners, 'chief' is a word that you should not only use correctly but also understand in all its stylistic and historical nuances. You should be able to recognize its use in various registers, from the highly formal language of a Supreme Court ruling to the more casual, yet still authoritative, tone of a newspaper editorial. As an adjective, you might use 'chief' to create a sense of gravitas or to signal a definitive ranking of priorities. For example, 'The chief architect of the peace treaty was praised for his diplomatic skill.' Here, 'chief' implies not just that he was the most important, but that he was the primary creator or 'head' of the project. You should also be sensitive to the etymological roots of the word, coming from the Old French 'chef' and the Latin 'caput,' meaning 'head.' This connection helps explain why the word is so deeply tied to concepts of leadership and physical or metaphorical 'heads' of things. At this level, you should also be aware of the subtle differences in how 'chief' is used in different varieties of English. For instance, its use as an informal term of address is more common in the UK and Australia than in the US. You should also be able to use 'chiefly' to qualify statements with precision, such as 'The failure was chiefly due to a lack of communication, though other factors played a role.' This ability to balance and weight different factors in a sentence is a hallmark of C1 proficiency. You should also be prepared to discuss the word's cultural history, including its use in colonial contexts and the modern efforts to use more inclusive language in certain professional and sporting environments.

At the C2 level, you have a complete and nuanced mastery of the word 'chief.' You can use it with total flexibility, understanding its role in everything from archaic literary texts to the most modern corporate jargon. You are aware of its potential for irony or sarcasm when used as a term of address, and you can use it yourself to convey a specific tone. In your own writing, you use 'chief' as a precision instrument to establish hierarchy and focus. You might use it in complex structures like 'Chiefly by virtue of its location, the city became a hub for trade.' You understand the word's full range of collocations and can use them to sound like a native speaker, or even a highly educated specialist. You are also aware of the legal and constitutional implications of titles like 'Chief Justice' or 'Commander-in-Chief' and can discuss these concepts in depth. Furthermore, you are sensitive to the ongoing linguistic shifts surrounding the word, such as the debate over its use in sports team names or as a generic title in organizations that are moving toward flatter hierarchies. You can analyze how the word 'chief' functions as a 'head' word in linguistic theory, and you can appreciate its use in poetry or high literature to evoke themes of power, leadership, and primacy. At C2, 'chief' is not just a vocabulary word; it is a conceptual tool that you use to describe and analyze the structures of power and importance that define human society and thought.

Practice it Examples Notes & Tips

chief in 30 Seconds

Chief is a noun meaning a leader or head of an organization, such as a police chief or a tribal leader, representing high authority.
As an adjective, chief means the most important or primary, used to highlight the most significant element among several options or factors.
The word is commonly found in professional titles like CEO (Chief Executive Officer) and is used in formal writing to prioritize main points.
It is important to distinguish chief from chef, as they have different meanings and pronunciations, and to remember the plural form is chiefs.

The word chief is a versatile and powerful term in the English language, functioning primarily as both a noun and an adjective. At its core, it signifies the highest rank, the most important position, or the primary focus of a situation. When you encounter it as a noun, it refers to a person who holds the highest authority within a specific group, organization, or community. Think of a police chief, a tribal chief, or a chief of staff. In these contexts, the word conveys leadership, responsibility, and the power to make final decisions. As an adjective, it modifies a noun to indicate that the noun is the most significant or principal among several options. For example, if someone says their 'chief concern' is safety, they are highlighting that while they may have many concerns, safety stands above all others in importance.

The Noun Form: A person with the highest rank or authority. It is often used as a formal title in professional hierarchies, such as the Chief of Police or the Chief Executive Officer. It implies a level of seniority where the individual is responsible for the actions and welfare of those beneath them.

The fire chief directed the emergency response team with calm precision during the crisis.

Historically, the term has deep roots in social structures. In many indigenous cultures, a chief is a hereditary or elected leader who provides spiritual, political, and social guidance. In modern corporate environments, the 'C-suite' (Chief Executive Officer, Chief Financial Officer, etc.) represents the pinnacle of the business hierarchy. The transition of this word from tribal leadership to corporate management illustrates its enduring association with the concept of being at the 'head' of a body of people. It is important to distinguish this from other leadership terms like 'manager' or 'supervisor,' as 'chief' usually implies the absolute top of the pyramid rather than a middle-management role.

The Adjective Form: Meaning 'most important' or 'main.' It is frequently used in academic and professional writing to prioritize one factor over others. For instance, 'The chief cause of the revolution was economic inequality.'

Lack of funding was the chief obstacle to completing the project on schedule.

In everyday conversation, you might hear people use 'chief' as an informal way to address a friend or a stranger, though this is more common in certain dialects like British or Australian English. However, in American English, using 'chief' as a casual address can sometimes come across as condescending or overly familiar, so it is best to stick to its formal and descriptive uses. The word carries a certain weight and gravitas; it is not a light word. Whether you are discussing the Chief Justice of the Supreme Court or the chief ingredient in a recipe, you are signaling to your listener that they should pay close attention to what follows because it is the most significant element of the discussion.

The chief negotiator for the union refused to back down on the demand for better healthcare.

Synonym Nuance: While 'main' and 'principal' are synonyms, 'chief' often carries a connotation of hierarchy or leadership that 'main' does not. A 'main road' is just a big road, but a 'chief concern' feels like it has been chosen as the leader of all concerns.

The chief architect of the building wanted to ensure that every window provided a view of the park.

Her chief ambition in life was to travel to every continent before she turned forty.

In summary, 'chief' is a word that demands respect. It identifies the head of a group or the heart of an issue. Understanding its dual nature allows you to navigate both formal organizational charts and complex descriptive narratives with ease. It is a foundational word for anyone looking to describe leadership or importance with precision and authority.

Using the word chief correctly requires an understanding of its grammatical role as either a noun or an adjective. As a noun, it functions like any other person-noun, but it often carries a title-like quality. When you use it as a title before a name, it should be capitalized. For example, 'Chief Inspector Morse' or 'Chief Joseph.' When used as a general noun, it often takes the definite article 'the,' as in 'The chief of the department.' It is important to note that 'chief' as a noun can be pluralized to 'chiefs.' A common spelling error is to write 'chieves,' but the correct plural form is 'chiefs.' This noun is countable, meaning you can have one chief or many chiefs.

Noun Usage Patterns: Typically used in the structure '[Title] + [Name]' or 'The chief of [Organization].' It can also stand alone if the context has already established which group is being discussed.

The chief of the medical staff reviewed the patient's records before the surgery.

As an adjective, 'chief' is almost exclusively used in the attributive position, which means it comes directly before the noun it modifies. You will rarely see it used in the predicative position (after a linking verb like 'is'). For instance, you would say 'This is my chief complaint,' but you would almost never say 'My complaint is chief.' If you want to express that something is the most important using a predicative structure, you would typically use synonyms like 'primary' or 'main.' This makes 'chief' a very specific tool for emphasizing importance within a noun phrase. It is also a non-gradable adjective; something cannot be 'more chief' or 'the most chief.' It either is the chief element or it is not.

Adjective Usage Patterns: Used in the structure '[Adjective] + [Noun].' Common pairings include 'chief concern,' 'chief executive,' 'chief aim,' and 'chief ingredient.' It acts as a ranking word.

The chief difficulty we faced was the extreme weather in the mountains.

In professional and academic writing, 'chief' is often used to introduce the most significant point in an argument. Phrases like 'Chief among these factors is...' allow a writer to signal hierarchy clearly. This is a more sophisticated way of saying 'The most important factor is...' and is highly effective in essays and reports. Furthermore, the word is frequently found in compound nouns that have become standard titles. 'Commander-in-Chief' is a prime example, referring to the person who has supreme command of a nation's military forces. In these cases, the word 'chief' is often hyphenated or part of a fixed phrase that should not be altered.

The chief editor of the newspaper decided to run the story on the front page.

Collocations to Remember: Chief executive officer (CEO), chief financial officer (CFO), chief operating officer (COO), chief of staff, chief concern, chief reason, chief among.

His chief responsibility is to manage the company's international sales team.

The chief witness in the trial provided a detailed account of the events.

When you are speaking, the word 'chief' is pronounced with a long 'e' sound (/tʃiːf/). It rhymes with 'brief' and 'leaf.' Mastering the pronunciation is key, as mispronouncing it as 'chef' (/ʃef/) can lead to significant confusion in a professional setting. By practicing these sentence patterns and paying attention to the word's position, you can use 'chief' to add clarity and authority to your English communication, whether you are writing a formal report or leading a team meeting.

The word chief is ubiquitous in several specific domains of modern life. One of the most common places you will hear it is in the world of business and corporate governance. The 'C-suite' is a term used to describe the top-ranking executives in a company, and almost all of these titles begin with 'Chief.' You will hear people talk about the CEO (Chief Executive Officer), the CFO (Chief Financial Officer), and the CTO (Chief Technology Officer). In these contexts, 'chief' signifies the ultimate level of decision-making power within a department or the entire corporation. When a company announces a 'new chief,' it is a major news event that can affect stock prices and company culture.

Corporate Media: News outlets like the Wall Street Journal or Bloomberg frequently use 'chief' to refer to corporate leaders. Example: 'The chief of the tech giant defended the company's privacy policy before Congress.'

The chief financial officer reported a twenty percent increase in quarterly profits.

Another major area where 'chief' is frequently heard is in public service and law enforcement. In the United States and many other countries, the head of a local police department is called the 'Police Chief' or 'Chief of Police.' Similarly, the head of a fire department is the 'Fire Chief.' In these roles, the word carries a sense of public duty and community leadership. You will often see these individuals being interviewed on the local news during emergencies or community events. The title is a mark of respect and indicates that the person has spent many years rising through the ranks to reach the top position.

Law Enforcement and Safety: Commonly heard in police procedurals, news reports, and city council meetings. Example: 'The police chief held a press conference to discuss the recent drop in crime rates.'

As the chief of the local fire department, he was responsible for the safety of the entire town.

In the realm of politics and law, the word is equally prominent. The 'Chief Justice' of the Supreme Court is the highest-ranking judge in the United States, presiding over the most important legal cases in the country. In the executive branch, the 'Chief of Staff' is one of the most powerful positions in the White House, acting as the gatekeeper to the President. When you hear these titles on political talk shows or read them in political analysis, they represent the inner circle of power. The adjective form is also common in political discourse, as politicians debate the 'chief causes' of inflation or the 'chief benefits' of a new policy.

The Chief Justice administered the oath of office to the incoming president.

Academic and Scientific Research: In research papers, 'chief' is used to identify primary variables or findings. Example: 'The chief finding of the study was that sleep deprivation significantly impairs cognitive function.'

The chief scientist at the laboratory announced a breakthrough in renewable energy technology.

The chief concern for environmentalists is the rising temperature of the oceans.

Finally, you will encounter 'chief' in literature and history. Whether it is a 'tribal chief' in a historical novel or the 'chief antagonist' in a play, the word helps to establish hierarchy and importance in storytelling. It allows authors to quickly signal who is in charge or what the most important conflict is. By paying attention to these different contexts—business, public service, law, and literature—you will see how 'chief' serves as a fundamental building block for describing the structures of our world and the priorities of our lives.

The word chief is a frequent source of confusion for English learners, primarily due to its spelling, pronunciation, and similarity to other words. One of the most common mistakes is confusing 'chief' with 'chef.' While they look somewhat similar, they are entirely different words. A 'chef' (/ʃef/) is a professional cook, usually the head of a kitchen. A 'chief' (/tʃiːf/) is a leader or the most important part of something. Confusing these two in writing or speech can lead to humorous or embarrassing situations. For example, saying 'I want to speak to the chef of police' would imply you want the police department's cook, rather than its leader.

Spelling and Pronunciation: Chief (leader) has an 'i' before 'e' and is pronounced with a 'ch' sound like 'church.' Chef (cook) has no 'i' and is pronounced with a 'sh' sound like 'shoe.' Remember: 'I' is for 'Important leader' in Chief.

Incorrect: He is the chef executive officer. (Correct: chief)

Another common error involves the pluralization of 'chief.' Many English nouns that end in '-f' or '-fe' change to '-ves' in the plural (like leaf/leaves or wife/wives). However, 'chief' is an exception to this general rule. The plural of 'chief' is simply 'chiefs.' Writing 'chieves' is a common mistake even for native speakers who are over-applying the '-ves' rule. Keeping this exception in mind will help your writing look more professional and accurate. Additionally, learners often struggle with the placement of 'chief' when it is used as an adjective. As mentioned before, it must come before the noun. Saying 'The reason is chief' is grammatically incorrect in modern English; you must say 'The chief reason is...'

Pluralization Mistake: Incorrect: The tribal chieves met to discuss the treaty. Correct: The tribal chiefs met to discuss the treaty.

Incorrect: My chiefly concern is the cost. (Correct: chief)

There is also a subtle mistake involving the word 'chiefly.' While 'chief' is an adjective, 'chiefly' is an adverb meaning 'mostly' or 'mainly.' Learners sometimes use 'chiefly' as an adjective (e.g., 'my chiefly concern') or 'chief' as an adverb (e.g., 'I am chief interested in...'). It is important to keep these parts of speech distinct. 'Chief' describes a noun, while 'chiefly' describes a verb or an adjective. For example, 'I am chiefly interested in history' is correct, as is 'My chief interest is history.' Using the wrong form can make your sentences feel clunky and unnatural.

Incorrect: The chief reason for the delay was rain. (This is actually correct, but people often use 'main' when 'chief' would be more precise in a formal context.)

Confusion with 'Principal': 'Chief' and 'Principal' are often interchangeable as adjectives, but 'Principal' as a noun usually refers to the head of a school. You wouldn't call a school principal a 'school chief' in most English-speaking countries.

Incorrect: The chief of the high school gave a speech. (Correct: principal)

Incorrect: He is chief responsible for the error. (Correct: chiefly)

Finally, be careful with the informal use of 'chief' as a term of address. In some cultures, it can be seen as patronizing or even offensive, particularly when used toward someone of a different ethnic background. It is always safer to use a person's name or a more neutral term like 'sir' or 'ma'am' if you are in a professional or formal setting. By avoiding these common pitfalls—the chef/chief confusion, the pluralization error, the adjective/adverb mix-up, and the insensitive term of address—you will be able to use 'chief' with confidence and precision.

The English language offers a variety of synonyms for chief, each with its own subtle nuances and appropriate contexts. When 'chief' is used as an adjective meaning 'most important,' the most common alternatives are 'main,' 'principal,' 'primary,' and 'key.' While 'main' is the most general and casual of these, 'principal' and 'primary' are often preferred in academic or formal writing. 'Key' is frequently used in business and journalism to highlight a crucial factor (e.g., 'a key ingredient' or 'a key witness'). Choosing the right synonym depends on the level of formality you wish to convey and the specific noun you are modifying.

Chief vs. Main: 'Main' is more common in everyday speech (e.g., 'the main road'). 'Chief' sounds more formal and often implies a hierarchy of importance (e.g., 'the chief reason').

The principal advantage of this method is its low cost compared to other options.

When 'chief' is used as a noun to refer to a leader, synonyms include 'head,' 'leader,' 'director,' 'manager,' and 'commander.' 'Head' is a very versatile word that can be used in almost any context (e.g., 'head of the family,' 'head of the department'). 'Leader' is more general and can refer to someone who inspires others, regardless of their official title. 'Director' and 'manager' are specific to corporate or organizational structures. 'Commander' is typically reserved for military or emergency service contexts. Using 'chief' instead of these words often emphasizes the person's absolute authority or their position at the very top of a specific hierarchy.

Chief vs. Primary: 'Primary' often suggests the first in a sequence or the most basic level (e.g., 'primary education'). 'Chief' suggests the most important in a group of similar things.

Our primary objective is to ensure that all students feel safe and supported in the classroom.

In some cases, 'foremost' or 'leading' can be used as alternatives to 'chief' as an adjective. 'Foremost' implies being at the very front or being the most prominent (e.g., 'the foremost expert in the field'). 'Leading' suggests being ahead of others or being the most successful (e.g., 'the leading manufacturer of electric cars'). These words add a sense of excellence or competitive advantage that 'chief' does not necessarily convey. On the other hand, if you want to describe something that is secondary or less important, you would use antonyms like 'minor,' 'subordinate,' 'secondary,' or 'incidental.' These words help to create a clear contrast with the 'chief' element of your discussion.

He is considered the foremost authority on Renaissance art in the world today.

Chief vs. Major: 'Major' means large or important, but there can be many 'major' factors. 'Chief' usually implies there is only one that is the most important.

The major cities of the region are all connected by a high-speed rail network.

Understanding these alternatives allows you to vary your vocabulary and avoid repetition. If you have already used 'chief' in a paragraph, you might switch to 'principal' or 'main' in the next sentence to keep your writing engaging. By mastering the subtle differences between these synonyms, you can express yourself with greater precision and tailor your language to the specific needs of your audience and the context of your communication.

Common Mistakes

Writing 'chieves' as the plural of chief. → chiefs
Unlike many words ending in 'f,' chief does not change to 'ves' in the plural. This is a common irregular pattern that must be memorized.
Pronouncing 'chief' like 'chef'. → /tʃiːf/ (ch-eef)
Chief starts with a 'ch' sound and has a long 'ee' vowel. Chef starts with a 'sh' sound and has a short 'e' vowel. They are completely different words.
Using 'chief' after the verb 'to be' (e.g., 'The reason is chief'). → The chief reason is...
As an adjective, 'chief' is almost always used before the noun it describes. It is not typically used as a predicate adjective.
Confusing 'chief' with 'principal' in a school context. → The school principal
While both mean 'most important,' the head of a school is almost always called a 'principal,' not a 'chief.'
Using 'chiefly' as an adjective (e.g., 'my chiefly concern'). → my chief concern
Chief is the adjective form; chiefly is the adverb form. Use 'chief' to describe a noun and 'chiefly' to describe a verb or another adjective.

Tips

I before E

Remember the rule 'I before E, except after C.' Since 'chief' has an 'h' before the 'ie,' the 'i' comes first. This will help you avoid the common misspelling 'cheif.'

Adjective Placement

When using 'chief' as an adjective, always place it before the noun. Say 'the chief reason,' not 'the reason is chief.' This is a specific rule for this word that differs from many other adjectives.

Professional Titles

Learn the 'C-suite' titles like CEO, CFO, and CTO. Knowing that the 'C' stands for 'Chief' will help you understand corporate hierarchies and business news more easily.

Chief vs. Chef

Practice the 'ch' sound in 'chief' (/tʃiːf/) and the 'sh' sound in 'chef' (/ʃef/). Distinguishing these two is vital for clear communication, especially in professional settings.

Formal Writing

Use 'chief' in your essays to introduce your most important point. Phrases like 'Chief among the factors...' add a sophisticated and authoritative tone to your writing.

No -ves

The plural of 'chief' is 'chiefs.' Do not follow the pattern of 'leaf/leaves.' This is a common mistake that even advanced learners make, so keep it in mind.

Be Respectful

Be aware of the cultural sensitivity surrounding the word 'chief' in relation to Indigenous peoples. Use the word as a professional title or to describe importance, but avoid using it as a casual nickname.

Vary Your Language

While 'chief' is a great word, don't over-use it. Switch to 'main,' 'primary,' or 'principal' to keep your writing and speaking varied and interesting for your audience.

Use 'Chiefly'

Don't forget the adverb 'chiefly.' It is a very useful word for qualifying your statements, such as 'The problem was chiefly economic.' It sounds more professional than 'mostly.'

Context Clues

When you hear the word 'chief,' look for context clues. If the speaker is talking about a department or a rank, it's likely a noun. If they are talking about a reason or a problem, it's likely an adjective.

Memorize It

Mnemonic

Remember that a Chief is the head of a group. Think of the 'C' in Chief standing for 'Commander' or 'Captain.' Also, remember 'I before E' to spell it correctly: 'The Chief is an Important Entity.'

Visual Association

In some cultures, particularly in the UK or Australia, 'chief' can be used as an informal term of address. However, in most professional environments, it is better to use your boss's name or their official title. Using 'chief' can sometimes sound sarcastic or overly familiar, so use it with caution.

No, 'chief' is only capitalized when it is part of a formal title before a name, such as 'Chief Inspector Miller.' When used as a general noun (e.g., 'the police chief') or as an adjective (e.g., 'the chief reason'), it should be written in lowercase.
