refers to two very different phenomena. First, it can refer to the way speakers use a language in their lives. There are different kinds of us-age, for example, everyday, informal usage; academic usage; formal us-age, etc. In everyday usage, for example, we may say or hear statements such as, â€œsomeone left their key on the table,â€ or â€œawesome, dude,â€ while the same meanings in more formal usage may be given as, â€œsomeone left his or her key on the table,â€ or â€œthat is quite excellent, my friend.â€ More narrowly, â€œusageâ€ refers to what many people consider â€œgood grammarâ€: using lay and lie correctly, not saying ainâ€™t, avoiding double negatives. In this latter sense, usage represents the linguistic equivalent of good manners.
