同伙
tóng huǒ · HSK 7
accomplice
👥 同 same + 伙 gang/partner = people in the same gang, an accomplice
同 means same; 伙 means gang, crew, or partner (as in 伙伴). Someone in your same crew is a colleague at best, a co-conspirator at worst.
同 — 冂 enclosure + 一 + 口 mouth
Originally depicted multiple mouths gathered under one cover or enclosure, suggesting people speaking together in agreement. From this image of voices joining, it came to mean 'same,' 'together,' or 'alike.' The shared cover symbolizes unity.
伙 — person radical 亻 + fire 火
伙 combines 亻 (person) with 火 (fire), originally referring to a group of people sharing a cooking fire — a mess unit of soldiers or travelers. From this it broadened to mean 'companion,' 'partner,' or 'group,' and is now common in words like 伙伴 (partner) and 伙计 (mate).
