bombast

The story of 'bombast' is one of metaphorical inflation. It originated from the Greek 'bómbux', imitating the humming of a silkworm, which evolved to mean cotton or padding in Latin and Old French. In the 16th century, English adopted 'bombast' to refer literally to the soft cotton material used for stuffing or padding garments. The critical semantic shift occurred when this literal sense of physical padding was applied figuratively to language: speech or writing that is artificially inflated with grandiose words to appear more substantial, much like a padded doublet. Thus, the modern abstract meaning perfectly captures the concept of verbose, empty rhetoric that is puffed up with self-importance.

Structure: bombast (Unsegmentable) The word is a simplex loanword. Its core form 'bombast' entered English as a whole unit from Old French 'bombace', meaning 'cotton wool'. This, in turn, came from Latin 'bombax' (cotton), likely derived from Greek 'bómbux' (silk/silkworm), a word of imitative origin suggesting a humming or buzzing sound.
