The word "internal" originated from the Latin word "internus", which means "within, inward, internal". It is derived from the combination of two Latin elements: "inter" meaning "between" or "among" and "nus" meaning "inward" or "inner". Over time, the word evolved into English as "internal" in the late 15th century, retaining its original meaning of something that is within or pertaining to the inside.
