A2 adjective #3,000 最常用 3分钟阅读

useful

Something that helps you do a job or solve a problem.

Explanation at your level:

Something is useful if it helps you. A pen is useful for writing. A map is useful for finding your way. If you have a problem, a useful thing helps you fix it. You can say, 'This book is very useful for my English class.'

When you need to finish a task, you look for useful things. For example, a calculator is a useful tool for math. You can also give useful advice to a friend. It means the information is good and helps them do something better.

In this level, useful often refers to resources or skills. You might say, 'Learning to cook is a very useful skill.' It implies that the thing has practical value in your daily life. We often use it with 'very' or 'quite' to describe how much help something provides.

At this level, you can use useful to describe abstract concepts like 'useful data' or 'a useful strategy'. It is a reliable adjective for professional contexts. You might also hear 'come in useful', which is a common phrasal construction for future utility.

As an advanced learner, you can use useful to nuance your arguments. Instead of saying 'good', you can specify that something is 'highly useful' or 'not particularly useful'. It is frequently used in academic writing to evaluate theories or methodologies. You might discuss the 'useful application' of a new scientific discovery.

At the mastery level, useful is a staple of analytical discourse. You might explore the 'utility' (the noun form) of a concept, but 'useful' remains the go-to adjective for clarity. It is used in literary criticism to describe the function of a character or a motif. It is precise, functional, and essential for clear communication across all domains of English.

When we call something useful, we mean it has a purpose. It is not just sitting there looking pretty; it is actively helping us finish a task, learn something new, or solve a tricky problem.

Think of your favorite Swiss Army knife or a search engine. These are perfect examples because they provide a specific benefit. You use them to make your life smoother or more efficient.

In conversation, you might say, 'That was a useful tip!' This means the advice you received actually helped you improve. It is a very positive word that highlights the value of an object, a person's help, or even a piece of information.

The word useful comes from the Middle English word use, which traces back to the Old French user and the Latin usus, meaning 'to use' or 'enjoyment'.

The suffix -ful is a Germanic addition meaning 'full of'. So, literally, something useful is 'full of use'. It has been part of the English language since the 14th century, evolving from its Latin roots to become the handy adjective we use today.

It is fascinating how words like this stay consistent over hundreds of years. While our tools have changed from wooden plows to smartphones, the need to describe something as 'full of use' has remained exactly the same.

You can use useful in almost any setting, from a casual chat with friends to a formal business meeting. It is a highly versatile word that describes both physical objects and abstract concepts like advice or data.

Commonly, we pair it with nouns: useful tool, useful information, or useful addition. It sits comfortably in the middle of the register scale—neither too fancy nor too slangy.

Be careful not to confuse it with 'helpful'. While they are similar, helpful usually describes a person or an action, while useful is more often used for things, tools, or information.

1. Useful idiot: A derogatory term for a person perceived as propagandizing for a cause without fully understanding the cause's goals.

2. Come in useful: To be helpful at a later time. Example: 'Keep that rope; it might come in useful later.'

3. Make yourself useful: A command to help out with chores. Example: 'Stop sitting around and make yourself useful!'

4. Useful life: The estimated time an asset is expected to be usable. Example: 'The car has reached the end of its useful life.'

5. Of little use: Something that doesn't help much. Example: 'That map was of little use in the storm.'

Useful is a standard adjective. It does not have a plural form because it describes a quality. To make it stronger, you can use adverbs like very, extremely, or quite.

Pronunciation-wise, it sounds like 'YOO-sful'. The 's' is unvoiced, like in 'hiss'. The stress is on the first syllable.

It rhymes with youthful (if you stretch it) or words ending in -ful like truthful or plentiful. Remember to focus on the 'yoo' sound at the start, which is a common stumbling block for some learners.

Fun Fact

It has been in English since the 1300s.
