auto
UK: ˈɔːtəʊ | US: ˈɔːtoʊ
n. 1. Short for "automobile"; a car.
n. 2. Short for "autobiography"; a written account of one's own life.
adj. 3. Acting independently or automatically (e.g., auto-pilot).
The word "auto" originates from the Greek autos (αὐτός), meaning "self." It entered English via Latin and French, retaining its core meaning of independence or self-operation. In modern usage, it prefixes compound words (e.g., autobiography, automobile) and stands alone as a noun (car) or adjective (automatic). Its evolution reflects technological and linguistic simplification—from "horseless carriage" to "auto."
