(also bombasine, bambazine), 1550s, from French bombasin (14c.) “cotton cloth,” from Medieval Latin bombacinium “silk texture,” from Late Latin bombycinium, neuter of bombycinius “silken,” from bombyx “silk, silkworm,” from Greek bombyx. The post-classical transfer of the word from “silk” to “cotton” may reflect the perceived “silk-like” nature of the fabric, or a waning of familiarity with genuine silk in the European Dark Ages, but cf. bombast.
