半年
bàn nián · HSK 1
half a year
📅 半 (half) + 年 (year) = half a year
半 means half and 年 means year, so 半年 literally reads as half-year. The compound is fully transparent: just stack the two characters' meanings together.
半 — 八 (split) + 牛 (ox/cow)
半 originally depicted an ox (牛) being divided in two, shown by the splitting strokes 八 on top. The image of cleaving an ox down the middle gave rise to the meaning 'half' or 'to divide into halves'. The modern sense of 'half' or 'partial' comes directly from this ancient act of splitting.
年 — grain 禾 over person 人 (oracle bone)
Originally a pictograph of a person carrying a bundle of harvested grain on their back, representing the yearly grain harvest. Because harvests came once a year, the character shifted from meaning 'harvest' to meaning 'year.' The modern form 年 obscures the original 禾 (grain) + 人 (person) structure.
