Phraseology

In linguistics, phraseology is the study of set or fixed expressions, such as idioms, phrasal verbs, and other types of multi-word lexical units (often collectively referred to as phrasemes), in which the component parts of the expression take on a meaning more specific than, or otherwise not predictable from, the sum of their meanings when used independently. For example, ‘Dutch auction’ is composed of the words Dutch ‘of or pertaining to the Netherlands’ and auction ‘a public sale in which goods are sold to the highest bidder’, but its meaning is not ‘a sale in the Netherlands where goods ar

A phraseme, also called a set phrase, fixed expression, multiword expression (in computational linguistics), or more specifically idiom, is a multi-word or multi-morphemic utterance whose components include at least one that is selectionally constrained or restricted by linguistic convention such that it is not freely chosen.

Verbosity, or verboseness, is speech or writing that uses more words than necessary. The opposite of verbosity is succinctness.
