bombast

Etymology and origin of the English word bombast

Pronunciation

  • IPA: /ˈbɒmbæst/ (UK); /ˈbɑmbæst/ (US)[1]

Etymology

It is an alteration of obsolete bombace “raw cotton, cotton padding”,[2][3][4] borrowed from Old French bombace (“cotton, cotton wadding”),[3][4][5] from Medieval Latin bombax (“cotton”),[5][4][6] itself an alteration of Latin bombyx (“silk, silkworm”),[5][3] from Ancient Greek βόμβυξ (bómbux).[5][3] Barnhart suggests the final -t came from bombast, the past participle of an obsolete verb bombase “to stuff with cotton”.[4]

Earliest recorded meaning

Raw cotton, and cotton wool used to pad clothes (1568–1572).[7][3]

Semantic evolution

From padding that swelled out a garment, the word was transferred to padded, inflated language with little substance (1589).[7][3][4] The verb to bombast “to render grandiose” was already in use by 1573,[7][4] and the adjective bombastic followed in 1704, after earlier bombastical (1649).[4] The literal sense is now obsolete.[6]
