IPA: /ˈtʃʌkər/
KK: /ˈtʃʌkər/
A person who throws something, especially in a sport like cricket where they may throw the ball instead of bowling it.
The chucker surprised everyone with his unusual throwing style during the game.
Chucker is derived from the verb 'chuck' (originating from Middle English 'chukken', meaning to throw or toss) with the suffix '-er' (meaning a person who performs an action). Therefore, a 'chucker' is a person who throws or tosses something.
Think of someone who 'throws' ('chuck') something — the '-er' indicates that this person is doing the action. A chucker is simply someone who chucks or tosses.
