The word "personal" refers to something that is related to or concerning an individual. It often pertains to one's private life, feelings, or opinions, as opposed to things that are public or general. When something is described as personal, it usually indicates that it is subjective and specific to a particular person.
The word "personal" comes from the Latin word "personalis," which means "of a person." It is derived from "persona," meaning "mask, character, person." The term evolved into the Middle English "persoun," which eventually became "personal" in the modern English language.
