IPA: /ˈsiːlɪŋ/
KK: /ˈsiːlɪŋ/
The upper surface of a room that covers the space below it, often made of materials like plaster or tiles.
The ceiling in the living room is painted white.
Ceiling comes from the Old French 'ceiling' (meaning a covering or a roof), which is derived from the verb 'ciel' (meaning to cover). The word refers to the upper interior surface of a room, essentially serving as a covering for the space below.
Imagine the 'covering' ('ciel') that protects the room from above — that's what a ceiling does.
