IPA: /ˈfɪmləs/
KK: /ˈfɪlm.ləs/
Describing something that does not use or contain film, often referring to photography or media.
The new digital camera is filmless, allowing users to take pictures without needing any film.
Filmless → It is formed from "film" (from Old English *filme*, meaning a thin layer or membrane) and "-less" (meaning without). The word "filmless" means without film or lacking a film layer.
Think of being 'without' ('-less') a 'thin layer' ('film') — that's why filmless means lacking a film.
