Input: Consider Input: Question: Possible Duplicate: What is the difference between an expression and a phrase? Difference between "phrase" and "idiom" What is the difference between a phrase, an idiom and an expression? I am looking for the context where one is more appropriate than the rest. I've been using idiom and phrase more or less interchangeably. 
Answer: This question asks nearly the same thing. This is the difference between an idiom and a phrase: A phrase is "a small group of words standing together as a conceptual unit", while an idiom is "a group of words established by usage as having a meaning not deducible from those of the individual words". So, the difference is that an idiom as an established meaning not directly linked to the individual words. Any idiom is a phrase. As an example, "raining cats and dogs" is both an idiom and a phrase. "A herd of cats" is a phrase but not an idiom. Expression has about the same meaning as phrase, except it is usually used of a phrase which is in common use. So an idiom is a certain sort of expression, which in turn is a subset of phrase: idiom > expression > phrase.

Output: yes


Input: Consider Input: Question: I'm trying to find different ways of saying that "You don't have to be a rocket scientist", but I can't seem to get any good ideas. I got a variation, "You don't have to be a brain surgeon...," but are there any others ways. It doesn't have to follow the routine of "You don't have to...". 
Answer: It's not like you're inventing the weel.

Output: no


Input: Consider Input: Question: The question is quite straightforward: Which of the following is preferable? "I keep myself up-to-date on the latest technology." "I keep myself up to date on the latest technology." 
Answer: The simple answer is that the non-hyphenated version is more appropriate - and more commonly used - in the example sentence that you give. The hyphenated version is more commonly seen as a compound adjective, sometimes as a jargon phrase. Indeed, I have seen it used as a perjorative, sarcastic term, although that is not common usage. So in summary, up-to-date is used as an adjective describing a condition or status of an object or document, while up to date is used to describe a state of mind or a fashion.


Output: no
