" The way in which words and phrases are used in speech or writing; style."
"In linguistics, phraseology describes the context in which a word is used. This often includes typical usages/sequences, such as idioms, phrasal verbs, and multi-word units. Phraseological units are (according to Prof. Kunin A.V.) stable word-groups with partially or fully transferred meanings (e.g., "to kick the bucket")."
I don't have any more time just now, but I'm sure one of our experts in linguistics can lend you a hand.
