Why “bloviate” is a great word
To speak or discourse at length in a pompous or boastful manner. From American English blow (in the informal sense 'to boast, speak idly') + the connective -i- + the verbal suffix -ate, by analogy with words like deviate; first attested in U.S. newspapers in 1845. Unlike pontificate (which presumes a pulpit of authority) or ramble (which suggests a meandering, forgetful path), to bloviate is to erect a gilded palace of words upon a foundation of hot air. It is the florid cadence of a stump speech promising everything, the sonorous drone of a pundit filling airtime with nothing, the performative erudition of a bore holding court—the audible spectacle of ego inflating itself with the breath of its own voice.
