Origin / Etymology

Borrowed from French gemmule, from Latin gemmula (“small bud; small gem”), from gemma (“bud of a plant; gem, jewel; thing made of precious stones”) (further etymology uncertain; possibly from Proto-Indo-European *ǵenh₁- (“to beget, give birth; to produce”), but see further at that entry) + -ula (feminine form of -ulus (diminutive suffix)).
