The term "signature word" does not have a distinct etymology as it is a combination of two separate words. "Signature" comes from the Latin word "signatura", meaning "a sign or mark", while "word" originates from the Old English word "word", which means "speech" or "promise". The combination of these words simply refers to a word that serves as a distinctive mark or indication of something.
