What does blowhard mean?
A blowhard is a person who boasts loudly and persistently, talking at great length about their own achievements, opinions, or expertise while typically possessing far less substance than their swagger suggests. The word is informal and distinctly derogatory, carrying an implication of empty noise rather than genuine accomplishment — a blowhard 'blows hard,' producing much wind but little of value. It is most often applied to public figures such as politicians, pundits, and executives, though it suits any overbearing conversationalist. The term originated in nineteenth-century America as colloquial insult vocabulary and has remained remarkably stable in both form and meaning ever since. Related terms include windbag, which emphasizes tedious verbosity, and braggart, which stresses boasting itself; blowhard combines both qualities. Because it vividly captures the gap between self-presentation and reality, it remains a favorite of critics, journalists, and anyone describing a tiresome loudmouth.
nounA person who talks boastfully and at length about themselves or their opinions without knowing as much as they claim.
- A person who boasts or brags loudly and persistently, often exaggerating their knowledge, achievements, or importance.

Born in 19th-century America as pure insult slang, 'blowhard' literally paints the braggart as someone blowing hot air — a word so useful it has barely changed in 150 years.

Etymology of blowhard
Blowhard arose in American English in the mid-nineteenth century as straightforward compound slang, joining 'blow' with 'hard' to suggest someone who emits an impressive amount of hot air. Its first recorded uses date to around the 1850s, when it appeared in American newspapers and colloquial writing as a term of contempt for boasters. The root verb 'blow' traces back through Old English 'blāwan' to the Proto-Germanic '*blē-', which also yields relatives such as 'blast' and 'bluster'. The word has changed little since its coinage, remaining a stable piece of informal American vocabulary adopted more widely across the English-speaking world.
How blowhard is actually used
Informal and mildly derogatory; used to criticize someone perceived as arrogant and talkative rather than substantively knowledgeable. Common in American English, though understood throughout the English-speaking world.
Easily confused with blowhard
A windbag merely talks at excessive length, while a blowhard specifically boasts and exaggerates his own importance or knowledge.
