群
ぐん · gun · JLPT N3 · noun
group
🐑🐑 群 = 君 lord + 羊 sheep: a flock of sheep following its leader
The right side 羊 means sheep, and sheep move in flocks, so the character came to mean group or crowd. 君 (kun) gives the sound, which became ぐん (gun), as in 群衆 ぐんしゅう, crowd.
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.
