What does heavyweight mean?
Heavyweight has two broad uses: a literal one involving substantial weight or size, and a figurative one describing exceptional importance or influence. In sport, a heavyweight is an athlete or participant in the heaviest weight class; as an adjective, heavyweights compete for a heavyweight title or occupy a heavyweight division. More often, however, the word is metaphorical. A political heavyweight is a powerful or influential figure, and a heavyweight report or controversy is one of major significance. In business and media, the expression similarly identifies a person or issue of exceptional consequence. The register is generally neutral, though some uses, particularly phrases such as “big name,” sound informal. British and American usage differ little. A useful distinction is that importance is the usual modern focus, not physical size.
A person or organization of exceptional importance or influence; also, an athlete or participant in the heaviest weight class.
"Several political heavyweights supported the proposed reform."
The metaphorical sense is especially common in political, business, and media contexts. The sporting sense refers to the heaviest division in a weight-class sport.
Of exceptional importance or influence; belonging to or involving the heaviest weight class; or having comparatively great weight or size.
"The network assembled a heavyweight legal team for the case."
When used figuratively, this adjective implies substantial authority, influence, or significance rather than mere prominence.
The plural is commonly used for groups of influential people, athletes in the heaviest weight class, or objects distinguished by considerable weight.
"The tournament brought in several international heavyweights."
A political heavyweight is not merely famous: the metaphor implies enough influence to shift the balance of an entire organization.
