糊涂
hú tu · HSK 7
muddled
🍯 糊 = paste + 涂 = smear; thoughts pasted and smeared together = muddled, confused
糊 (hú) is paste or sticky porridge; 涂 (tu) is to smear or daub. Together they describe a mind whose ideas are stuck and smudged into one blur, so it means muddled or silly. Bonus: hú tu sounds a bit like who-too, the reply of a confused person.
糊 — rice 米 + 胡 (phonetic)
A semantic-phonetic compound: 米 (rice) gives the meaning, since 糊 originally referred to rice paste or congee used as glue. 胡 supplies the sound. The meaning later extended to 'paste,' 'to stick,' and figuratively 'muddled' or 'blurred,' as in 糊涂.
涂 — water radical 氵 + 余 (phonetic)
涂 is a phono-semantic compound: the 氵 water radical hints at the meaning, while 余 supplies the sound 'tu/yu'. Originally it referred to a river name and to mud or wet earth, which extended to the verb sense 'to smear, daub, or apply' something wet like paint or mud onto a surface.
