The word "regular" refers to something that is consistent, orderly, or follows a pattern. It can describe actions that happen at fixed intervals or things that are standard and expected. For example, if someone has regular exercise habits, it means they work out consistently and follow a set routine. In a broader sense, "regular" can also imply conformity to established norms or rules.
The word "regular" comes from the Latin word "regularis," which means "arranged according to rule." This is derived from "regula," meaning "a rule" or "a straight stick." The prefix "re-" indicates repetition or emphasis, thus reinforcing the concept of something being in order or conforming to a standard.
