萄

Top grass radical anchors 萄 in the plant family — appropriate since the word only appears in 葡萄 grape, the climbing vine itself a sprawling plant. Both 葡 and 萄 carry 艹 to mark them as botanical, a tidy paired-character word where each half wears the same plant hat.

Bottom 匋 — a person 勹 bent over a pottery wheel 缶 — is the older simple form of 陶 pottery. Here it serves purely as the phonetic frame supplying táo. 萄 only ever appears in 葡萄 grape; both syllables are bound morphemes of a foreign loanword (Old Persian budāwa), each given a botanical hat plus phonetic body.
