I need a phrase which has a meaning of a question that is very easy to answer and requires very little thought. I think it might have something to do with word no-brainer.

I don't know if a no-brainer question is grammatically correct since both are nouns.

Is it actually correct or not? Is there any alternative?

  • "No-brainer" is a noun, and does not require "question" to follow if the meaning is clear in context.

There is nothing wrong with "no-brainer question".

A compound noun is a noun that is composed of two or more nouns. When there are two nouns like "no-brainer question", the first noun functions as a noun modifier.

Another broadly used idiom is "rocket science" which means:

an activity requiring considerable intelligence and ability (esp in the phrase not exactly rocket science)


If you say "This isn't a rocket science question", it means it is no-brainer.

    Good answer but personally I would expect a question that's "Not rocket science" to still require a little more thought than a "no-brainer". Like "no-brainer" is a 1 on the difficulty scale, and "not rocket science" is a 3 perhaps, out of 10 that is. Jun 27, 2016 at 7:55

You may be able to apply self-evident here.

Not needing to be demonstrated or explained; obvious:
self-evident truths

    I don't think that most no-brainer questions are self evident. If you asked me my favourite film I'd say "That's a no brainer - 2001 A Space Odyssey!". That's in no way self-evident though, even to people who know me. Jun 27, 2016 at 7:57

    Indeed a no-brainer for the questioner is different from a no-brainer for the answerer.
