业余
yèyū · HSK 4
amateur
🎨 业 = work/profession + 余 = surplus/leftover → leftover work = hobby
业 means profession or work; 余 means surplus or extra. Together, 业余 literally reads as work-surplus — the time left over after your real job. That leftover work becomes amateur, recreational, or hobby pursuits.
业 — top 业 (originally a notched board)
Originally a pictograph of a notched wooden board hung in ancient classrooms or temples to support bells and chimes. The notches inspired meanings of 'work' and 'profession,' as such boards were tools of trade and study. Today it means business, occupation, or undertaking.
余 — roof 亼 + wooden post/pillar
Originally a pictograph of a simple thatched shelter or hut supported by a central post, 余 meant 'lodging' or 'temporary dwelling.' It was later borrowed phonetically to write the first-person pronoun 'I/me,' which became its dominant meaning. The 'surplus/remainder' sense developed through its use as a loan for 餘.
