半 (bàn) means "half" with 5 strokes, radical 十 (ten), HSK 1 on the new exam.
Pronunciation
Meaning
Primary: half
Etymology
Oracle-bone origin
半 is not attested in oracle bone script but appears in bronze inscriptions as a compound of 八 (to divide, split) on top and 牛 (ox) below. The image is of an ox being divided in two, a direct representation of halving a large thing.
Form evolution
Bronze forms show 八 clearly splayed above a recognisable 牛. Seal script (篆书) regularised both components, and clerical script (隶书) flattened the top splay into two short slanting strokes while the 牛 below lost its curved horns. Modern 楷书 keeps this structure but the bottom element no longer looks like an independent 牛.
How the meaning evolved
The original concrete sense of cutting an ox in half generalised quickly to mean half of anything, then to partial or incomplete states. Modern uses like 一半 (one half), 半天 (half a day, or a long while), and 半夜 (midnight) all descend from this core idea.
Cultural note
The idiom 半途而废 (to give up halfway) preserves the sense of partiality, and learners often misread the bottom component as 羊 (sheep) or 平 because the 牛 has been visually absorbed into the character.
Mnemonic
Two halves divided by ten — half
