brook

To brook something means you will not allow or put up with it.

Explanation at your level:

The word brook is a very special word. It is a verb, which means it is an action. When you say 'I will brook no...' it means you say 'I will not let this happen.' It is a very serious word. You do not use it when you are playing with friends. You use it when you are the boss and you want things done your way. It is a bit like saying 'No!' very loudly and clearly.

When you use the verb brook, you are talking about what you will allow. Most of the time, we use it to say what we will not allow. If a teacher says, 'I will brook no talking in class,' they mean they will not allow any talking at all. It is a formal way to show you are in charge. It is a short, strong word that sounds very serious.

The verb brook is a formal way to say 'tolerate.' It is used almost exclusively in negative sentences to show that someone is very firm. You will often see it in phrases like 'brook no delay.' This means the person is not willing to wait. It is common in formal writing, such as news reports or historical books, to describe people who are very strict or powerful. It is not used in everyday conversation, so be careful when you use it!

Brook is a sophisticated verb that carries a sense of authority. It is a synonym for 'tolerate' or 'endure,' but it is much more specific. It is used to describe a refusal to accept something that stands in the way of a goal. For example, 'The CEO brooked no interference from his board.' This shows the CEO is in total control. It is a great word to use in formal essays or when you want to emphasize that someone has zero patience for obstacles or disagreement.

At the C1 level, you recognize that brook is a marker of formal, often literary, register. It functions as a declarative verb of power. Unlike 'tolerate,' which can imply a passive acceptance, 'brook' implies an active, forceful rejection of anything that threatens one's intent. It is frequently paired with abstract nouns like 'dissent,' 'opposition,' or 'equivocation.' Using this word effectively allows you to convey a sense of unyielding resolve. It is a perfect choice for academic writing or formal rhetoric where you need to describe a character or a policy that is uncompromising.

Mastering brook requires an understanding of its etymological shift from 'to enjoy' to 'to endure.' In modern English, it is an archaism that has survived in specific, high-register contexts. It is a 'gatekeeper' word; using it correctly signals a high degree of comfort with the nuances of English power dynamics. It is almost exclusively used in the negative, as the positive usage ('I brook his presence') is now considered archaic and potentially confusing. When you use brook, you are invoking a sense of historical authority. It is most effective when describing a situation where a boundary is being set that is absolute and non-negotiable. It is a stylistic choice that elevates the tone of your writing to a level of formal, almost Shakespearean, intensity.

Word in 30 Seconds

  • Verb meaning to tolerate or allow.
  • Almost always used in the negative.
  • Very formal and literary register.
  • Rhymes with book.

Hey there! Let's talk about the word brook. It sounds a bit old-fashioned, doesn't it? That's because it is! When you use the verb brook, you are being very firm about what you will and will not accept.

Think of a strict leader or a very serious teacher. If they say, 'I will brook no nonsense,' they are telling you that they absolutely refuse to tolerate any bad behavior. It’s a powerful way to draw a line in the sand. You won't hear this at a casual lunch with friends, but you might read it in a history book or hear it in a dramatic movie.

The key thing to remember is that brook is almost always used with the word 'no.' It’s rarely used in a positive sense. You wouldn't say 'I brook the rain,' but you would definitely say 'The captain brooked no delay.' It’s all about showing authority and setting firm boundaries.

The history of brook is actually quite fascinating because it has two different meanings that come from two different roots! As a noun, a brook is a small stream, coming from Old English broc. But as a verb, it comes from the Old English word brucan, which meant 'to use, enjoy, or possess.'

Over hundreds of years, the meaning of brucan shifted. In Middle English, it evolved to mean 'to digest' or 'to put up with.' If you could 'digest' something, you could handle it! Eventually, it settled into the modern sense of 'tolerating' or 'enduring' something.

It’s a great example of how language changes over time. While the 'stream' meaning stayed the same, the 'verb' meaning became more formal and restricted. It’s like a linguistic time capsule that reminds us how people used to talk about 'enjoying' or 'digesting' circumstances. Isn't it cool how a word can carry such a long journey behind it?

Using brook correctly is all about the register. Because it is a formal and slightly literary word, using it in a text message to your friend might sound a bit strange or overly dramatic. It is best saved for formal writing, speeches, or describing someone with a very commanding presence.

The most common way to use it is in the phrase 'brook no [noun]'. Common nouns that follow include delay, interference, dissent, argument, or excuse. Notice how these are all things that someone in charge would want to stop immediately.

If you are writing a story and want to describe a character as powerful and unyielding, brook is your best friend. It signals to the reader that this person is not messing around. Just remember: keep it negative! If you try to use it in a positive sentence, it will likely sound confusing to native speakers.

While brook itself acts like a fixed expression, it appears in several strong collocations that function like idioms:

  • To brook no delay: To insist that something happens immediately.
  • To brook no interference: To refuse to let anyone get in the way.
  • To brook no argument: To shut down any debate or disagreement.
  • To brook no opposition: To be completely intolerant of anyone disagreeing with you.
  • To brook no excuses: To demand results without listening to reasons why something wasn't done.

These idioms are all about authority. They are the language of leaders, generals, and strict parents. Using them adds a layer of weight and seriousness to your sentences that simple words like 'allow' or 'tolerate' just can't match.

Grammatically, brook is a regular verb. Its past tense is brooked and its present participle is brooking. It is almost always used as a transitive verb, meaning it needs an object to follow it (e.g., 'He brooked no delay').

Pronunciation is straightforward: /brʊk/. It rhymes with book, look, cook, took, and hook. The 'oo' sound is short, like in 'foot.' It’s a single-syllable word, so there’s no stress pattern to worry about—just hit it hard and clear!

Because it is a formal verb, you won't see it used in continuous tenses very often. You wouldn't usually say 'He is brooking no delay.' Instead, you use the simple past or present: 'He brooks no delay' or 'He brooked no delay.' Keep it simple and direct for the best effect.
