～港
～こう · ～kou · JLPT N2 · noun
port
⚓🚢 港 = 氵 water + 巷 lane: a water lane where ships come in
It's the 港 in Hong Kong (香港, fragrant harbour). As a suffix, ～港 names a port: 横浜港 is Yokohama Port and 神戸港 is Kobe Port. The water radical 氵 marks it as a place on the sea.
港 — water radical 氵 + 巷 (alley)
A semantic-phonetic compound: 氵 (water) gives the meaning, while 巷 (alley) supplies the sound. Originally referred to a branch of a river or a small waterway, then extended to mean a sheltered inlet where boats could moor — a harbor or port.
