Sense: noun/1

Broadcaster is the broadest of these terms and includes anyone who presents on radio or TV, from news readers to talk-show hosts. Sportscaster is a narrower term used almost exclusively in North America for someone who covers sports events on air. Announcer typically refers to a person who reads prepared material — such as starting lineups, weather updates, or traffic alerts — rather than giving spontaneous live commentary. Reporter gathers facts and presents news stories, often after the event has happened, whereas a commentator describes the action as it unfolds. For example, a sportscaster might say 'The quarterback drops back to pass,' while the announcer reads 'Third down, five yards to go.' The reporter would interview players after the game, not describe the play itself.

Etymology

LatinEnglish

Commentator comes from Latin 'commentator,' meaning 'one who discusses or writes upon a subject.' This traces back to the verb 'commentari' ('to consider thoroughly, to discuss'), built from 'com-' ('together') and 'mens' ('mind'). The word entered English in the 14th century, first referring to a writer of explanatory notes on scholarly or religious texts, and later broadened to include live-event describers in the age of radio and television.
