to swarm
🐑🐝 Radical 羊 (sheep) in 群: a flock bunches up, so 群がる = swarm together
群 combines 羊 (sheep) for meaning with 君 for sound, and means flock or herd. Add the verb ending がる to get to gather or swarm, as ants, fans, or crowds do. Use it when a group pushes toward one spot.
群 — 君 jūn (phonetic) + 羊 sheep (semantic)
群 is a phono-semantic compound. The 羊 (sheep) component gives the meaning — sheep naturally gather in flocks — while 君 (jūn) supplies the sound. From the literal sense of a flock, the meaning broadened to any group, crowd, or cluster of people or things.
