occasion
🎭 场合 = 场 (venue/field) + 合 (gather/fit) — a fitting venue
场 means an open ground or venue (think 广场 square, 操场 playground); 合 means to come together or fit. A 场合 is the gathering-place + fit: the specific occasion or situation where something takes place.
场 — earth 土 + 昜 (bright/rising)
Originally a flat open ground used for sun-drying grain or for ritual offerings, hence 土 'earth' as the meaning component. 昜 supplies the sound and hints at an open, sunlit space. The meaning broadened to any open area or venue, and as cháng it still refers to a threshing floor or a session/spell of something.
合 — 乛 (lid/roof) + 口 (mouth)
Originally a pictograph of a lidded vessel — a cover (亼) closing over an opening (口) — giving the core sense of 'come together, join, fit.' From 'fit/match' it extended to 'combine, unite, agree' and to measure-word uses. The reading hé reflects this 'joining' meaning.
