萄

It has no independent lexical usage and used exclusively in the compound 葡萄.

A phono-semantic compound, where the semantic element marks it as a plant, while 匋 supplies the sound.

艸 (grass, plant) — semantic component, indicates a plant or vine

匋 (pottery; kiln) — phonetic component, provides pronunciation (táo)

萄 never appears alone.

포도 (葡萄) — grape

포도주 (葡萄酒) — wine

포도원 (葡萄園) — vineyard

萄 is a textbook example of a bound morpheme used in an inseparable binome.

Neither 葡 nor 荼 functions independently. Meaning emerges only from the paired form.

This structure is typical of:

- loanwords

- plant names

- early phonetic transliterations

葡萄 is believed to be a phonetic transcription of a Central Asian / Iranian word. Introduced to China via the Silk Road during the Han dynasty.

荼 exists solely to complete the phonetic structure.

Unlike native plant names, this binome preserves its foreign sound structure, explaining why neither component developed independent meaning.
