means A person who fights with their fists, wearing padded gloves, under formal rules of weight class, rounds, and referee — whether as an athlete in the ring or a dog of the breed sharing the name.

from Straightforward agent noun: 'box' (to strike or fight with the fists) plus '-er,' the suffix that turns an action into a doer. The verb 'box' itself is old and murky in origin — it shows up in English for 'to hit' well before boxing was an organized sport, and nobody is certain exactly where it came from, though it's sometimes linked to words for a blow or cuff. The dog breed borrowed the name later, popularly said to be inspired by the way the dog plants its front paws and 'boxes' with them when it plays — a charming story, though breed historians treat it as tradition rather than confirmed fact.
