The Difference between the Verbs “Need” and “Require” (English)

Note: This post explores the differences between the verbs need and require. It may not explain all cases, but I hope it provides some insight that could be useful to English language learners or teachers.

Introduction: To Need or To Require?

Often, the verbs need and require can be used as synonyms (i.e. they are the same). However, through my years teaching English, I have occasionally come across sentences in which the verb "need" doesn't seem to fit. The purpose of this page is to explain those cases. Let's look at the below sentences, for example.

  • This job needs patience. (This seems wrong -- the job requires patience -- it doesn't need it).
  • The meeting will need at least 1 hour. (Wrong again -- the meeting will require an hour -- it doesn't need it)

This got me thinking -- what is the rule? What's the difference between the verbs need and require?

Firstly, let's look at a few examples of the verb need and how we can paraphrase the sentences.

  1. I need a glass of water. (= I want / desire / would like a glass of water because it's important)
  2. The cat needs some food. (= It wants / desires / would like food because it's important)

Judging by these examples, to need something requires volition (will). In other words, something that needs has to be alive; it has to be able to have needs that can be fulfilled. Compare:

  1. You need patience to be a doctor. (Correct = you, a person, can have needs)
  2. Being a doctor needs patience. (Wrong = 'Being a doctor', the subject, is a thing, not a person. It cannot need anything.)

One Exception: Personification

Personification is we talk about non-human objects (such as cars or trees) like they are alive -- for example: the stars danced in the sky. We use the verb need in this way sometimes too. For example.

  1. Your car needs oil.
  2. Your bathroom needs a cleaning.

In both these sentences, we seem to be giving the subjects (car, house) the ability to need something, as if it were a person. These may be exceptions to the above rule.

From the above, we can formulate this general rule: Living things can need while objects generally cannot need something.

So, if we go back to our first two sentences above ("This job needs requires patience. / The meeting will need require an hour."), we now have a reason why  'need' is unnatural: because the subjects cannot have needs. Next, there is one more distinction between the two verbs.

A Nuance: To Require = To Cause to Be Necessary

This is one of the definitions of require according to my Apple/Oxford dictionary. Again, let's look at two examples to illustrate this difference.

  1. My job requires computer skills. (Correct)
  2. I require computer skills. (Unnatural)

The first sentence is correct. Your job creates the need/requirement for computer skills. It is the cause of the need. Your job requires the skills, and you need the skills.

Think of it in the passive voice and ask yourself: why are computer skills required? Answer: Your job (not you).

This explanation also works well with our first two examples.

  • My job needs requires patience. (Correct -- Why is patience required? Answer: Your job)
  • The meeting will need require at least an hour. (Correct -- Why will an hour be needed? Answer: the meeting)

Reminder: To Need and Require Are Often Synonyms

Using the two rules above, we can see why the verbs can be used synonymously sometimes. Take another example:

  • My boss needs the report by 5 p.m. (Correct = Your boss wants/desires/would like it because it's important)
  • My boss requires the report by 5 p.m. (Correct = Why is the report required? Because of your boss. He has caused the requirement/necessity)

Summary and Closing

These are the two rules I believe can be helpful:

  1. Generally, living things need something.
  2. To require is to cause something to be necessary. Ask yourself Why is it required? The answer should be the subject of your sentence.

I'll admit, this is complicated, and there are a few exceptions that may not fit into this rule. Look at the sentence The soup needs more salt, for example. Firstly, the soup is an inanimate object without needs. Who needs the salt? You do. You need salt for your soup (this is a perfect sentence). Secondly, why is the salt required? It's because of you (not the soup -- it's important for you).  Following my rules, the sentence should be: I need/require salt for my soup. However, we say "The soup needs salt."

Why? Have we gotten lazy in our language? Or are we thinking of the soup as something that has needs? Am I totally wrong? Possibly. But there's no point worrying about cases when the flexibility allows the verb to be used in a different situation; instead, we only need to worry about sentences in which one verb cannot be used well. That's the point of this post.

Lastly, there may be some of you who see a sentence like "The meeting will need a break" and think it sounds fine. If so, you are less of a prescriptivist than I am. Be happy.

    Wow- excellent explanation. How can I join in so that I can receive newsletters, updates, comments etc. Looked around and couldn’t find any subscription icon/page

      Hello again. Do you use Facebook? That’s the main social media outlet I use to promote the site. There’s a link on the homepage. If you like the page, you will see updates regarding new posts (they are also listed on the main page). As the site is run entirely by one person (me), there aren’t any newsletters. Generally though, there’s a new post or two every week or so.

    thank you very much for the excellent post. I’m now much clearer about the difference of these two words.

    I have one idea just for a discussion:

    if the subject is functionally or emotionally related to human or human needs then it might be possible to use need as well.

    for example: the river needs a bridge. the computer needs a upgrade.

    thank you.

      That’s interesting. But can you give an example sentence of a subject that is not functionally or emotionally related to human needs?

      Learning a language needs requires patience. <-- This seems just as related to our needs as the river example.

    Understanding the context can help to identify which one we should use. To need means something up to us to do it or not and to require means something an obligation we must do it.

    Which word should be used in the following sentence –
    Please let me know if any help is needed/required ?

    1. MB (Posted on 3-14-2018 at 13:40) Reply

      Both make sense but have a slightly different nuance. “Please let me know if any help is needed” is preferable to me and sounds more helpful, as it is the same as “Please let me know if you need any help” (focusing on helping the person). On the other hand, “Please let me know if any help is required” is less personal. It sounds like less of a favour to the person, but more of a fulfillment of a requirement/duty of the task/job.

    His shirt needs a top button. The car needs a new bumper. The fence needs a new coat of paint. The job can’t “need” patience because it “demands” it. “Need” can’t be used in that sense: “We must do as the law requires/demands. Agency/volition has nothing to do with it; it’s a lexical difference you’ve invented an invalid rule to explain.

    1. mb Post author (Posted on 4-22-2018 at 12:47) Reply

      Please, go ahead then. Explain the lexical difference, as what you’ve written above is not clear.

    After looking at your two examples for “need” which don’t seem to fit for you, I just conclude that this is a dialect-based thing. In my dialect (which is pretty close to RP) they are both totally fine, and are things I would say myself.

      That’s fair. The more flexible language is, the better I suppose.

    What is the difference between: “I need you to do something” versus “I require you to do something”? Does former means a request and later indicates a command?

    1. mb Post author (Posted on 4-6-2021 at 09:38) Reply

      Hi. Though I’d never thought about it before, I would agree with your assessment. ‘I require you to’… sounds stronger and a little more formal. It’s probably the formality that makes it seem stronger — it sounds like something a powerful authority would say.

    Someone said the word require should be used professionally and the word need is unacceptable.
    The patient needs a wheelchair. This sentence is said to be incorrect when used professionally. The resident requires a wheelchair is said to be professionally correct.

    1. MB (Posted on 12-9-2021 at 14:49) Reply

      In sentences where either word is interchangeable, I agree that the ‘require’ sounds more professional.

        I’m confused I thought you mentioned that a living thing has a need and the work need should be used not require.

        1. mb Post author (Posted on 4-24-2023 at 09:52) Reply

          People can require things. The main difference is that non-living things (e.g. a meeting) cannot ‘need’ something.
