require
To need something or to make something necessary.
Explanation at your level:
When you require something, you need it. It is like saying 'I need' but it sounds a bit more serious. For example, 'Plants require water to grow.' Without water, they cannot grow. Use it when you talk about things that are very important.
You use require when something is necessary for a rule or a task. If a teacher says, 'This homework requires a pen,' it means you cannot use a pencil. It is a formal way to say 'need.' Remember, we use it for things that are mandatory or essential for success.
At this level, you will see require used in instructions and formal requests. It is common to see 'required' on forms or signs, like 'Safety glasses required.' It implies that there is an external rule or a specific condition that must be met. It is more precise than 'need' because it suggests a standard that must be satisfied.
In B2, you will notice require used in professional and academic writing. It is often used in the passive voice: 'You are required to submit your report by Friday.' This construction is very common in business. It conveys an obligation without sounding overly aggressive. It is a key word for expressing requirements in a workplace or academic environment.
At the C1 level, require is used to describe complex needs in abstract contexts. You might say, 'The situation requires a nuanced approach.' Here, it suggests that the circumstances demand specific qualities or actions. It is also used in legal contexts, such as 'The contract requires both parties to sign.' It denotes a binding necessity rather than a simple desire.
At the C2 level, you can appreciate the subtle nuance of require compared to synonyms like 'necessitate' or 'demand.' While 'demand' implies force, 'require' implies a formal or logical necessity. It is frequently used in high-level literary and academic discourse to define the parameters of a system or a philosophical argument. Understanding its etymological roots in 'seeking' allows you to use it in sophisticated ways, such as 'The resolution requires a re-examination of our core values,' where it implies a logical or moral imperative.

Hey there! Let's talk about require. Think of it as a more formal, serious version of the word 'need.' When you say something is required, you are saying it is absolutely essential.
We use require when there is a rule to follow or a goal to reach. For example, if you are baking a cake, the recipe might require three eggs. Without those eggs, the cake just won't turn out right! It's not just a preference; it's a necessity.
You will hear this word a lot in school, at work, or when reading official documents. It carries a sense of duty or obligation. If a task requires your full attention, you cannot do it while distracted. It is a powerful word that helps clarify exactly what is needed to get things done successfully.
The history of require is quite fascinating! It comes from the Old French word requerre, which itself traces back to the Latin requirere. This Latin word is a combination of re- (meaning 'again' or an intensive prefix) and quaerere (meaning 'to seek' or 'to ask').
So, originally, to require meant to seek something out again or to ask for something with authority. Over the centuries, the meaning shifted from simply 'asking' to 'demanding' or 'needing' as a matter of necessity. It is a cousin to other English words like request, inquire, and acquire, which all share that same Latin root for 'seeking.'
It is fun to think that every time you say you require something, you are using a word that has been traveling through languages for over a thousand years. It evolved from a simple request into a word that defines our modern rules and requirements.
Using require correctly is all about understanding the level of formality. It is much more common in writing and professional settings than in casual conversation. If you are talking to a friend, you might say 'I need a pen,' but in a formal email, you might write 'This document requires your signature.'
Common collocations include require attention, require assistance, and require permission. You will often see it used in passive voice, such as 'Safety gear is required in this area.' This is a very standard way to state rules clearly.
Remember that require is usually followed by a noun or an infinitive verb (e.g., 'The job requires patience' or 'They require you to arrive early'). Avoid using it for small, unimportant things; save it for when something is truly necessary or mandatory.
While require is a formal verb, it appears in several fixed expressions. 1. As required: Used to mean 'whenever it is necessary.' Example: 'Add salt as required.' 2. Required reading: Books or documents that you must read. Example: 'This manual is required reading for new staff.' 3. Require little introduction: Used for someone or something famous. Example: 'This legendary singer requires little introduction.' 4. Require a steady hand: Used for tasks needing precision. Example: 'This delicate repair requires a steady hand.' 5. Require the utmost care: Used for dangerous or fragile tasks. Example: 'Handling these chemicals requires the utmost care.'
The verb require is a regular verb. Its past tense and past participle form is required, and its present participle is requiring. It is a transitive verb, meaning it usually needs an object to complete its meaning.
Pronunciation-wise, it is two syllables: re-QUIRE. The stress is on the second syllable. In IPA, it is /rɪˈkwaɪər/. It rhymes with words like admire, fire, hire, inspire, and retire. Make sure to clearly pronounce the 'r' at the end for a natural sound.
A common pattern is require someone to do something. For instance, 'The law requires drivers to wear seatbelts.' Notice how we use the 'to' infinitive after the object. It is a very consistent pattern that you will see in legal and academic English constantly.
