Where does the word explain come from?

The Word "explain" originates from the Latin verb "explicare," which means "to unfold" or "to clarify." This Latin term is composed of the prefix "ex-" meaning "out" and "plicare," meaning "to fold." Over time, it evolved into the Old French "expliquer" before entering the English language in the late Middle Ages. The term conveys the idea of making something clear or understandable by revealing its underlying details.
