[EX Q]: Possible Duplicate: What is the difference between a phrase and a clause? Can you give me an easy description of the differences in meaning between clause, phrase, and sentence?.
[EX A]: Phrase, clause and sentence are three of the structural units that create meaning. A phrase is a word or words that don't have much meaning on their own. If I suddenly utter the phrase My brother, you'll wonder why I said it, but if I say My brother drives, you'll feel I've said something that has meaning. There's a completeness about it, because it contains the verb drives. That makes it a clause, but it is also a sentence. But I needn't stop there. I can go on to say something else, almost without drawing breath. I can say My brother drives, but he doesn't drive very well. I've added another clause, and together they, too, make a sentence, joined by the little word but. It is perhaps helpful to see two or more clauses joined together as a clause complex, although sentence in general use describes both single and multiple clauses.

[EX Q]: I am writing a poem for school. The verse with the word I need to change is this: 7 hours is too long In much too short a day You really don't care if you get an answer wrong Because you don't care a _____ about radioactive decay The only thing I can think of is the word shit, but that word is too offensive. I have tried looking for inoffensive alternatives at Real Life English's Not so Offensive Alternatives to Bad Words in English, and wordhippo but these alternatives do not sound great, especially in a poem. I also searched for don't care a ___ on the free dictionary by Farlex's idioms website and 'don't care a fig' came up, alongside some other suggestions I tried from the autofill suggestions. Most worked literally, but I am looking for a more clever and poetic word or words that could be used in a way that relates to my poem. I am not just looking for any old answer. I do not want you to simply search for 'don't care a' on google. I want suggestions that fit creatively into my poem.
