What does bluster mean?
Bluster describes loud, forceful, and often boastful speech that signals more strength or certainty than the speaker truly possesses. As a verb, it means to speak or behave in this noisy, intimidating manner — politicians who bluster about retaliation they have no intention of carrying out, or bullies who bluster to hide their insecurity. As a noun, bluster refers to that talk itself, especially when it proves empty: promises and threats that dissolve on contact with reality. The word also has an older, literal sense, describing violent, gusty weather — winds that bluster across a coastline. Connotations are almost always unflattering when applied to people: bluster suggests hollowness beneath the noise, which is why commentators reach for it when rhetoric outpaces action. Derived forms such as the adjective 'blustery' (commonly used of windy days) and 'blustering' keep it active in both everyday and literary English, making it a precise tool for distinguishing mere noise from genuine force.
To talk in a loud, aggressive, or boastful manner, typically in a way that exaggerates one's confidence, power, or intent.
"He blustered that he would sue them all, but no legal papers ever appeared."
Almost always pejorative when applied to people; implies the speaker's forcefulness masks weakness.
Loud, aggressive, or boastful talk that lacks real force or substance; also, violent, gusty motion of wind or weather.
"His threats turned out to be pure bluster, and nobody took them seriously."
In the weather sense the word is somewhat literary; in modern usage the 'empty talk' sense dominates.
The plural is rare; the noun is usually uncountable in its 'empty talk' sense, so a singular mass-noun treatment is standard.
"Amid all the blusters of the campaign season, few concrete policies emerged."
Shakespeare loved 'bluster' so much he used it repeatedly — and its earliest recorded uses are literally about storms, not people.

Etymology of bluster
Bluster first appeared in English in the sixteenth century, with early uses applying to violent weather before extending to human behaviour. Its ultimate origin is uncertain; lexicographers generally treat it as likely imitative in nature, coined to echo the sound of roaring wind, rather than as a borrowing from another language. Shakespeare used the word several times, helping fix both its literal and figurative senses in the language.

How bluster is actually used
The verb sense applied to people carries a strongly negative connotation, implying that the speaker's noise compensates for a lack of real power, courage, or substance. The weather sense ('the wind blustered') is neutral and literary in flavour. Both the noun and verb appear in journalism and political commentary, where 'empty bluster' is a stock phrase for rhetoric unlikely to be backed by action.
