I really didn't know how to name this thread so I apologize about it. My question is: what is the linguistic term that refers globally to the words "vocabulary", "words", "phrases", "collocations", "expressions", "jargon", "idioms", "lexicon" etc?
I am doing an article on this and in the process of writing my paper when I put the word "vocabulary" I feel like I am referring only to single-words (e.g.: coincidence) opposite to when I write "phrase" which refers to more than one word without a verb/subject (e.g.: many thanks) or when I write "expression/idiom" it refers, generally speaking, to more words with a verb/subject (e.g: She is pulling my leg). The problem is I need to refer to these in one word, what is that word? I was thinking of "lexicon" but I am not sure. Is there something like "linguistic inventory"? I really need this word.
Thank you a lot. I hope that wasn´t so confusing.
