full-length
UK: ˌfʊl ˈlɛŋθ | US: ˌfʊl ˈlɛŋθ
adj. covering the entire length or duration (e.g., a full-length movie)
adj. (of clothing) reaching to the ankles or floor (e.g., a full-length dress)
The compound "full-length" combines "full" (Old English full, meaning "complete") and "length" (Old English lengþu, derived from lang "long"). It emerged in the 18th century to describe objects or works (e.g., mirrors, garments, films) that occupy or depict their entire intended span without abbreviation. The logic is transparent: "full" intensifies "length" to emphasize totality.
