film
UK: fɪlm | US: fɪlm
n. a thin layer or coating
n. a motion picture; movie
vt. to record or capture on video or photographic film
The word film traces back to Old English filmen, referring to a thin membrane or skin. Over time, it evolved to describe any thin layer (e.g., oil film on water). In the late 19th century, with the invention of photographic and motion-picture technology, film was adopted to denote the flexible material used for recording images. By extension, it came to mean the recorded content itself (e.g., "watch a film"). The root logic revolves around thinness and layering, bridging physical and abstract uses.
