贪玩儿
tānwán r · HSK 7
Greedy
🎮 贪玩儿 = 贪 greedy + 玩 play = greedy for play, i.e. fond of fooling around
The 贪 part is the same greedy in 贪心 (greedy heart). Tack on 玩 (play) and the er-sound 儿, and a greedy appetite gets aimed at fun: someone who craves playtime and keeps goofing off.
贪 — 今 (jīn, phonetic) + 貝 (shell/money)
贪 is a phono-semantic compound. The bottom 貝 (shell) signals meaning, since cowrie shells were ancient money, hinting at greed for wealth. The top 今 supplies the sound. The character originally meant coveting riches and broadened to mean greedy or craving in general.
