The word "usage" refers to the way in which a word, phrase, or language is used. It encompasses the rules and conventions surrounding the application of language in different contexts. Moreover, it can also refer to a particular way of employing something, such as technology or tools, in practical settings.
The term "usage" originates from the Middle English word "usage," which came from the Old French "usage." This, in turn, is derived from the Latin word "usus," meaning "use" or "a way of using."
