🎬🎞️ 片 = sheet/slice (of film) + 子 noun suffix; a flat strip of film = a movie
片 originally means a thin flat slice or sheet, like a strip cut from something; film stock is exactly that, a long flat strip. Adding the 子 suffix turns it into the everyday noun for a movie or a roll of film.
片 — right half of 木 (tree split vertically)
Pictograph showing the right half of a tree 木 split down the middle, depicting a thin slice or slab of wood. From this came the meanings 'slice,' 'flat thin piece,' and by extension 'sheet' or 'card.' Its mirror image 爿 represents the left half.
子 — pictograph of a baby/child with arms out
子 began as a pictograph of a swaddled infant with a large head and outstretched arms, originally meaning 'baby' or 'child.' From there it broadened to 'son,' 'offspring,' and a respectful suffix for masters like 孔子 (Confucius). It also became one of the twelve earthly branches.
