# Welterweight

Welterweight is a weight class in combat sports. Originally the term welterweight was used only in boxing, but other combat sports like muay Thai, taekwondo, and mixed martial arts also use it for their own weight division system to classify the opponents. If used, welterweight is typically between lightweight and middleweight.

## Etymology

The first known instance of the term is from 1831, meaning 'heavyweight horseman', later 'boxer or wrestler of a certain weight' by 1896. This sense comes from earlier welter, 'heavyweight horseman or boxer' from 1804, possibly from c. 15th century welt, meaning 'to beat severely'.

## Boxing
### Professional boxing
