IPA: /ˈdɔːɡˌkætʃər/
KK: /ˈdɔgˌkæʧər/
A person whose job is to catch and remove stray dogs from public areas.
The dogcatcher arrived to help control the stray dog population in the neighborhood.
Dogcatcher → The word is formed from 'dog' (of uncertain origin, but likely from Old English 'docga', meaning a powerful breed of dog) and 'catcher' (from 'catch' which comes from Old Norse 'kappa', meaning to seize or capture, plus the suffix '-er' indicating a person who performs an action). A dogcatcher is a person who captures or seizes dogs, typically stray ones.
Think of someone who 'seizes' ('catch') dogs, and the '-er' means a person doing that action. This helps you remember that a dogcatcher is someone who captures dogs.
