Definition of bombast

: pretentious inflated speech or writing political bombast

Did you know?

The original meaning of bombast in English was "cotton or other material used as padding or stuffing." It is derived through Anglo-French bombés or bombace, from a Medieval Latin word (of various forms, including bambax and bombax) meaning "cotton plant, cotton fiber or wadding." Bombax was once thought to be a corruption of bombyx, a Latin (and ultimately Greek) word that means "silkworm" or "silk," although etymologists weren't certain why the shift from silk to cotton occurred. It turns out, however, that bombast's origins are more direct and unassuming: the Latin bombax is not a product of the silky bombyx but was borrowed from the Middle Greek bámbax, pámbax, which in turn probably traces back to the Middle Persian pambak ("cotton"). Bombast is no longer used in the sense of cotton padding or stuffing, but the word has been retained in modern English in a figurative sense referring to speech or writing that is stuffed or padded with pretense and unnecessary verbiage.

History and Etymology for bombast

earlier, "cotton or other material used as padding or stuffing," extension (with parasitic t) of bombace, bombage, going back to Middle English bombace, borrowed from Anglo-French bombés, bombace, borrowed from Medieval Latin bambac-, bambax, bombax (also banbax, bonbax) "cotton plant, cotton fiber or wadding," borrowed from Middle Greek bámbax, pámbax, going back to a Greek stem pambak- (as in pambakís "item of clothing, probably of cotton"), probably borrowed from Middle Persian pambak "cotton" (or from an unknown source from which both words were borrowed)

Note: At virtually all stages of this etymon's history there has been formal and semantic confusion with Latin bombyx "silk" and its congeners (hence the o in the English, French, and Latin forms; see note at bombazine), though the two words are very likely of distinct origin. The earliest European occurrence of the "cotton" word is pambakís, denoting an item of apparel in an epigram attributed to Myrinus (1st century b.c.e. or earlier) in the Palatine Anthology (VI, 254). In some manuscripts of Dioscorides' treatise on materia medica (1st century c.e.) bambakoeidḗs "cotton-like" is used in the description of a plant (other witnesses give bombykoeidḗs "silklike"). Greek bámbax and pámbax, as well as a derivative, bambákion, are attested in the 10th-century Byzantine encyclopedia Suda/Souda, which cites the epigram by Myrinus (see Suda On Line at The Medieval Latin forms are well attested in texts of the Salerno medical school, as the Tractatus de aegritudinum curatione, part of the now lost Breslau Codex Salernitanus (ca. 1200); see citations under bombyx, sense 2, in the Mittellateinisches Wörterbuch.
