体育场
tǐ yù chǎng · HSK 2
stadium
🏟️ 体育场 = body + nurture + field → sports field
体 (body) + 育 (nurture/raise) together mean physical education or sports. 场 (field/arena) marks the venue. So 体育场 literally reads as the field for physical training — a stadium.
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.
