渚
なぎさ · nagisa · JLPT N1 · noun
edge
🌊🏖️ water radical 氵 marks the wet edge; the 者 part gives the sound, like nagisa's shore where waves reach land
The water radical 氵 shows the character is about water, and 者 supplies the sound. Nagisa is the strip where sea water meets the shore, so the water side of the kanji matches the water's edge meaning.
