Tips

usage

As a verb 干 is blunter and more colloquial than 做. "What are you doing" is 你在干什么 (casual / a bit terse) vs. 你在做什么 (neutral). Tone of voice carries it: 你干什么 yelled is closer to "what the hell are you doing!"

register

Two charged senses reuse the same verb but stay slangy — the primary meanings (work / trunk / cadre / capable) are clean office and everyday vocabulary. As mainland slang 干 can mean "take out / kill" (干掉). As a standalone exclamation it is a crude vulgarity (closest to English "f**k!") — extremely common in Taiwan curses (usually written 幹 in traditional script). These slang reuses don't make the whole character vulgar; stick to 干活, 干部, 干杯 in polite company.

Components

ideograph

干 gàn

trunk; to do

Stylized residue of traditional 幹 — historically that character drew a tree-trunk graphic (倝 phonetic over 干). The 1956 reform discarded the trunk component and reused the simpler shield-graph 干 to write all three readings. The modern form no longer pictures a trunk; it inherits the shape of the shield character.

Filed under radical 十 (shí, #24) by convention. 十 is not a separate component in 干, so no strokes are highlighted.
