伙伴
huǒ bàn · HSK 4
companion
👥 伙 (fire/mess) + 伴 (companion) — fire-mates who share meals
伙 originally meant a squad sharing a cooking fire (the 火 radical is right there); 伴 means companion. Together: the people you share the fire and food with — your partners, your crew.
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).
伴 — person radical 亻 + half 半
A semantic-phonetic compound: 亻(person) gives the meaning and 半 (bàn, 'half') supplies the sound while also hinting at 'one of a pair.' The original sense was 'companion' or 'partner,' someone who is your other half, and from there it extended to 'accompany.'
