What does middleweight mean?
Middleweight is chiefly a boxing term for a competitor in the division between welterweight and light heavyweight. As a noun, it can name either the boxer or the weight class itself; as an adjective, it describes the class, its championship, or a bout. The term is used in British and American sporting English and is especially associated with professional boxing, although the label can appear in other combat sports where a middleweight category exists. “Middleweight” should not be understood as a fighter’s particular body type or as a substitute for saying someone has an average build: it refers to an established sporting division whose limits are set by the relevant rules and may vary across organizations. In phrases such as “middleweight champion,” the word works attributively, while “a middleweight” normally identifies a competitor. The compound reflects its straightforward construction from middle and weight. It is a useful term because it names a precise category in a sport in which weight classifications are central to matchups, titles, and records.
A boxer or combat-sports competitor in the middleweight class; also the weight class itself.
"The young middleweight moved up a division after a season of impressive performances."
When referring to the class or its title rather than to an individual competitor, the noun is normally singular.
Belonging to, relating to, or characteristic of the middleweight class.
"He won the middleweight championship after a series of decisive victories."
This use commonly occurs before words such as champion, title, division, and bout.
Used for multiple competitors in the class; the class or title itself is normally singular.
"Several middleweights are expected to contest the tournament."
In boxing, middleweight occupies the space between welterweight and light heavyweight—a name that defines competitive rank rather than any fighter's size.
