🎥📽️ 纪录 = record + 片 = film slice; a recorded film = documentary
片 (piàn) means a flat slice or film, the same character used in 照片 (photo) and 电影片. So 纪录片 is literally a record-film: footage that documents real events rather than fiction.
录 — 彐 (hand) + 氺 (water/threads)
Originally depicted a hand carving or inscribing characters, with the lower element suggesting shavings or marks. The early meaning was 'to carve' or 'to engrave', which extended to 'to record' or 'to write down'. Today it primarily means 'to record' or 'copy'.
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.
