解説 analysis in your Level:

At the A1 level, 'analysis' is a very advanced word, but you can understand it as a 'careful look' at something. Imagine you have a bag of mixed candies. If you look at them and count how many are red, how many are blue, and how many are green, you are doing a very simple analysis. It means you are not just looking at the bag, but you are looking at the parts inside the bag. In school, your teacher might show you a picture and ask you to talk about what is in it. This is the start of analysis. You are breaking the picture down into people, colors, and objects. You don't need to use the word 'analysis' yet, but you are doing the action. If you do see the word, just think: 'Someone is looking very closely to understand something better.' It is like being a detective with a magnifying glass. You are looking for details that other people might miss. Even at this early stage of learning English, understanding that some words describe 'thinking' actions is very helpful for your progress.

At the A2 level, you should start to recognize 'analysis' in your textbooks and school assignments. An analysis is a careful study of something. For example, if you are learning about the weather, an analysis of the rain might show which months are the wettest. In your English class, you might do an analysis of a short story by looking at who the main character is and where they live. It is more than just a summary; it is about finding the 'why' and 'how'. You might hear your teacher say, 'Let's do an analysis of this sentence.' This means you will look at the subject, the verb, and the object to see how the sentence is built. You can use the word 'analysis' when you talk about your homework or a project you are working on. It is a noun, so you 'do' an analysis or 'write' an analysis. Remember that it is a serious word, used for things that take time and thought. It is a great word to use to show that you are thinking deeply about your studies.

At the B1 level, 'analysis' becomes a key word for describing your work and thoughts more professionally. You are expected to move beyond simple descriptions and start explaining patterns. For instance, in a business context, you might perform a 'market analysis' to see if people will buy a new product. This involves looking at data and making a report. In science, you might perform an analysis of an experiment's results to see if your hypothesis was correct. You should also be aware of the plural form, 'analyses', and the verb form, 'analyze'. At this level, you can use phrases like 'based on my analysis' or 'a detailed analysis shows'. This makes your speaking and writing sound more logical and evidence-based. You will also see 'analysis' used in news articles about the economy or politics. When a journalist provides an analysis, they are explaining the deeper meaning of the news. Learning this word helps you participate in more complex conversations about how the world works.

At the B2 level, 'analysis' is a word you should use frequently and accurately in academic and professional writing. You should be able to distinguish between different types of analysis, such as 'qualitative analysis' (looking at qualities and meanings) and 'quantitative analysis' (looking at numbers and statistics). You are expected to conduct analyses that are 'thorough', 'critical', and 'objective'. For example, in a university essay, you wouldn't just describe a historical event; you would provide a 'critical analysis' of the causes and effects of that event. This means looking at different viewpoints and deciding which ones are most supported by evidence. You should also be comfortable using the word in the idiom 'in the final analysis', which is a sophisticated way to introduce your main conclusion. At this level, you understand that analysis is not just about breaking things down, but about synthesizing those parts into a new, deeper understanding. Your ability to perform and describe an analysis is a key indicator of your critical thinking skills in English.

At the C1 level, 'analysis' is a fundamental component of your intellectual toolkit. You use it to navigate complex, abstract, and highly technical topics. You are capable of performing 'meta-analysis' (an analysis of other analyses) and understanding the philosophical implications of different analytical frameworks. In a professional setting, you might lead a 'systems analysis' to improve a large organization's efficiency. Your use of the word is precise; you know when to use 'scrutiny', 'evaluation', or 'dissection' instead of 'analysis' to convey a specific nuance. You can follow and contribute to high-level academic debates where the 'method of analysis' is itself a topic of discussion. You recognize that every analysis is influenced by the perspective of the person performing it, and you can account for this bias in your own work. Whether you are analyzing a complex legal document, a nuanced piece of literature, or a massive dataset, your analysis is characterized by depth, rigor, and a clear logical structure. You use the word 'analysis' to signal a commitment to evidence-based reasoning and intellectual honesty.

At the C2 level, your mastery of 'analysis' is complete. You use the word and its derivatives with the same ease and precision as a highly educated native speaker. You can engage in 'discourse analysis', 'phenomenological analysis', or 'econometric analysis' at the highest levels of academia or industry. You understand the historical evolution of the term and how different schools of thought (like 'Analytical Philosophy') have shaped its meaning. Your analyses are not just reports of findings; they are original contributions to your field that can change how others understand a topic. You can effortlessly switch between different analytical registers, from a formal white paper to a sophisticated dinner party conversation. You use 'analysis' to deconstruct complex cultural phenomena, identifying the subtle interplay of power, history, and language. For you, analysis is a way of being in the world—a constant, rigorous engagement with information that seeks to uncover the deepest truths. You are also able to critique the limitations of analysis itself, recognizing where intuition or creativity might be more appropriate than a purely analytical approach.

analysis 30秒で

Analysis means breaking something complex into smaller parts to understand it better. It is a key skill in school, science, and business.
The word is a noun, and its plural form is 'analyses'. It is often used with verbs like 'conduct', 'perform', or 'provide'.
Common types include data analysis, market analysis, and literary analysis. It implies a serious, evidence-based approach rather than just a guess.
Be careful not to confuse the noun 'analysis' with the verb 'analyze'. Also, remember to use the preposition 'of' when describing what you are studying.

The word analysis is a noun that describes the process of breaking a complex topic or substance into smaller parts in order to gain a better understanding of it. Think of it like taking a clock apart to see how the gears work together. In everyday life, we perform an analysis when we look at our monthly spending to see where our money goes, or when a doctor looks at blood test results to check our health. It is a fundamental tool in science, business, and education because it allows us to move beyond a surface-level view and see the underlying patterns and causes of things.

Scientific Context: In a laboratory, an analysis might involve testing a chemical to see what elements it contains. Scientists use specific tools and methods to ensure their analysis is accurate and objective.
Business Context: Companies perform market analysis to understand what customers want. They look at sales data, competitor prices, and social media trends to make smart decisions about new products.
Literary Context: In school, you might do a literary analysis of a book. This means you look at the characters, the setting, and the themes to understand the message the author is trying to send.

The scientist's analysis of the soil revealed high levels of minerals necessary for plant growth.

Using the word 'analysis' implies a level of seriousness and detail. You wouldn't usually say you're doing an 'analysis' of what to eat for lunch unless you are being very funny or are a nutritionist. Instead, it is used for tasks that require logic, evidence, and careful thought. It is the opposite of a 'guess' or a 'quick look'. When you provide an analysis, people expect you to have evidence to support your findings.

A careful analysis of the situation showed that the problem was simpler than we first thought.

In modern technology, we often hear about 'data analysis'. This is the process of using computers to find patterns in huge amounts of information. For example, Netflix uses data analysis to suggest movies you might like based on what you have watched before. This type of analysis is changing how the world works, from medicine to sports. Even in sports, coaches use video analysis to help players improve their technique by watching their movements in slow motion.

The financial analysis predicted a significant growth in the tech sector over the next five years.

After a thorough analysis of the evidence, the detective identified the main suspect.

Our analysis of the feedback showed that customers want faster delivery times.

Using 'analysis' correctly involves understanding its grammatical role as a noun and the common verbs and adjectives that accompany it. It is most frequently the object of verbs like 'perform', 'conduct', 'provide', or 'carry out'. For example, you don't just 'do' an analysis in a formal report; you 'conduct a comprehensive analysis'. This elevates the register of your English and makes your communication more precise.

Common Verb Pairings: Verbs like 'require', 'suggest', 'reveal', and 'support' often follow 'analysis' as the subject. Example: 'The analysis suggests that we need to change our strategy.'
Adjective Modifiers: To describe the quality of the work, use adjectives like 'detailed', 'thorough', 'brief', 'statistical', 'critical', or 'preliminary'. Example: 'We are waiting for the final analysis.'
Prepositional Use: We usually say 'analysis of' something. Example: 'An analysis of the data' or 'An analysis of the poem'. We also use 'in the final analysis' as a fixed phrase.

The teacher asked for a written analysis of the historical event.

When writing at an A2 or B1 level, you might use 'analysis' to describe your school projects. As you move toward B2 and C1, you will use it to describe complex data sets, social trends, or philosophical arguments. It is important to distinguish between the noun 'analysis' and the verb 'analyze'. You *analyze* data to produce an *analysis*. Mixing these up is a common error for learners. Always check if you need an action (verb) or a thing (noun) in your sentence.

Our analysis indicates that the new software is much faster than the old version.

In professional settings, 'analysis' is often part of a compound noun. You might hear about 'risk analysis', 'gap analysis', or 'systems analysis'. These terms describe specific professional processes. If you are working in an office, knowing these specific types of analysis will help you understand your job requirements better. For example, a 'risk analysis' involves looking at what could go wrong in a project and finding ways to prevent those problems.

The company conducted a SWOT analysis to identify its strengths and weaknesses.

She provided a brilliant analysis of the political situation in her latest article.

Without a proper analysis, we are just guessing about the cause of the failure.

You will encounter the word 'analysis' in a variety of real-world environments, ranging from news broadcasts to academic lectures and corporate boardrooms. It is a staple of professional and intellectual discourse. When you watch the news, especially segments on the economy or politics, the anchor will often say, 'And now for some analysis from our expert.' This signals that the expert will explain the 'why' and 'how' behind the news events, rather than just reporting what happened.

On the News: 'The following is an analysis of the latest job market figures.' Here, it means an explanation of what the numbers mean for regular people.
In the Hospital: 'We need to send these samples for laboratory analysis.' In this case, it refers to the technical testing of biological materials.
In Sports Broadcasts: 'Let's look at the post-game analysis to see where the defense failed.' Commentators use this to break down the strategies used during the game.

The podcast offers a weekly analysis of current global events.

In university settings, 'analysis' is perhaps the most common word you will hear. Professors will ask for an analysis of a theory, a chemical reaction, or a historical period. It is the core of what students are expected to do: move beyond memorizing facts to understanding the relationships between those facts. If you are preparing for exams like the IELTS or TOEFL, you will often be asked to 'provide an analysis' of a graph or a short text. This requires you to describe the data and then explain what it signifies.

The weather channel provided an analysis of the upcoming storm's path.

In the tech world, 'analysis' is everywhere. Software developers perform 'requirements analysis' to figure out what a new app needs to do. Cybersecurity experts perform 'threat analysis' to see how hackers might attack a system. Even when you use a fitness app, it is performing an 'analysis' of your heart rate and steps to tell you how healthy you are. The word is so common because we live in an age of information, and information is useless without the analysis to make sense of it.

The documentary gives a deep analysis of how social media affects our brains.

During the meeting, the manager presented an analysis of last year's sales figures.

The expert's analysis helped the government decide on the new policy.

Even advanced learners of English make mistakes with the word 'analysis'. The most frequent errors involve its plural form, its confusion with the verb 'analyze', and the use of incorrect prepositions. Because the word has a Greek origin, it doesn't follow the standard English rule of adding '-s' or '-es' to make it plural. This often trips people up in both writing and speaking.

Pluralization Error: Mistake: 'We need to look at these two analysises.' Correct: 'We need to look at these two analyses.' The ending changes from -is to -es.
Noun vs. Verb Confusion: Mistake: 'I need to analysis this data.' Correct: 'I need to analyze this data.' Use the verb for the action and the noun for the result.
Preposition Errors: Mistake: 'An analysis about the results.' Correct: 'An analysis of the results.' While 'about' is sometimes used informally, 'of' is the standard academic and professional choice.

Incorrect: He did a great analyze of the book. Correct: He did a great analysis of the book.

Another common mistake is overusing the word. Sometimes learners use 'analysis' when they simply mean 'thought' or 'opinion'. An analysis requires a structured approach. If you are just giving your quick thoughts, 'opinion' or 'view' is better. Using 'analysis' for something simple can make you sound overly formal or even a bit pretentious. Additionally, be careful with the spelling of the verb: in American English it is 'analyze' (with a 'z'), while in British English it is 'analyse' (with an 's'). The noun 'analysis' is spelled the same in both.

The analysis was flawed because the data was old.

Finally, watch out for the phrase 'in the final analysis'. It is a useful idiom meaning 'when everything has been considered', but it is often used incorrectly as a synonym for 'finally' or 'in conclusion'. 'In the final analysis' should be used to introduce the most important point or the ultimate truth of a complex situation, not just to signal the end of a list. For example: 'In the final analysis, the success of the project depends on teamwork.'

The analyses (plural) performed by the two teams yielded different results.

You need to provide a more detailed analysis to support your claim.

The analysis of the crime scene took several days.

While 'analysis' is a powerful word, using it repeatedly can make your writing repetitive. Depending on the context, there are several synonyms and related words you can use to add variety and precision to your English. Understanding the subtle differences between these alternatives is key to reaching a higher level of fluency. Some words focus more on the 'looking' part, while others focus on the 'judging' or 'breaking down' part.

Examination vs. Analysis: An 'examination' is a close look at something. It is often more physical. You examine a patient or a document. An 'analysis' is more mental and involves understanding the parts.
Investigation vs. Analysis: An 'investigation' is usually done to find a specific answer or a hidden truth, like a crime investigation. An 'analysis' is broader and focuses on understanding how something works.
Evaluation vs. Analysis: An 'evaluation' is about deciding the value or quality of something. You evaluate a student's performance. An analysis is the step you take *before* the evaluation.

The detective's investigation led to a thorough analysis of the fingerprints.

Other useful alternatives include 'breakdown', 'scrutiny', and 'study'. 'Breakdown' is great for financial contexts (e.g., 'a breakdown of the costs'). 'Scrutiny' implies a very, very close and critical look, often by someone in authority. 'Study' is a more general term that can often replace analysis in academic contexts (e.g., 'a study of the local bird population'). By choosing the right word, you show that you understand the nuances of the English language.

The scrutiny of the government's budget revealed several errors in the analysis.

In the final analysis, choosing between these words depends on what you want to emphasize. If you want to emphasize the process of looking, use 'examination'. If you want to emphasize the result of understanding, use 'analysis'. If you want to emphasize the judgment of quality, use 'evaluation'. Mastering these distinctions will significantly improve your ability to express complex ideas clearly and effectively in any professional or academic setting.

A quick review is not enough; we need a deep analysis.

ヒント

Use 'an' not 'a'

Because 'analysis' starts with the vowel sound 'a', you must always use the article 'an'. Saying 'a analysis' is a common mistake that is easy to fix.

Learn the Verb

Make sure you also learn the verb 'analyze'. Using the noun and verb correctly will make your English sound much more natural and professional.

Stress the 'AL'

The most important part of the word is the second syllable. Practice saying 'an-AL-y-sis' until it feels natural. This is the key to being understood.

Be Specific

Instead of just saying 'analysis', use an adjective to describe it, like 'thorough', 'brief', or 'critical'. This adds more detail to your writing.

Critical Analysis

In university, a 'critical analysis' doesn't mean saying bad things. It means looking at both the good and bad parts and using evidence to support your views.

Data is Key

In a business setting, an analysis is only as good as the data it uses. Always mention where your data came from when presenting an analysis.

The Letter 'Y'

Remember that analysis is spelled with a 'y', not an 'i'. This is a very common spelling error for learners whose native language uses 'i'.

Listen for Context

When you hear 'analysis', listen to the words around it. They will tell you if it's about science, business, literature, or something else.

Final Analysis

Use 'in the final analysis' to start your concluding sentence in an essay. It sounds very sophisticated and clear.

Analyses

If you are talking about more than one study, use 'analyses'. Remember the pronunciation change to a long 'e' sound at the end.
