The word 'elective' is used to describe a course or activity that you can choose to take, rather than one that is required. For example, in school, you may have to take math, science, and English classes, but you may have the option to choose an elective like art or music. In healthcare, an elective procedure is one that is scheduled in advance and is not an emergency. In general, the word 'elective' is used to describe things that are optional or chosen by preference instead of being mandatory.
