欲深い
よくふかい · yokufukai · JLPT N1 · noun
greedy
💰 欲 (desire) + 深い (deep): desire so deep it never fills up, like a bottomless money bag
深 — water radical 氵 + 罙 (phonetic, depth)
深 combines the water radical 氵 with 罙, which depicts a hand reaching into a cave or hollow. Originally it described deep water, then broadened to mean 'deep' in any sense — distance, color, or feeling. The 氵 gives the meaning, while 罙 hints at both sound and the idea of reaching far in.
