IPA: /ˈmɛndər/
KK: /ˈmɛndər/
A person who repairs or fixes things that are broken or damaged.
The mender quickly fixed my broken shoe.
Mender → It is formed from "mend" (from Old French *mendre*, meaning to repair or fix) and "-er" (meaning a person who). A mender is a person who repairs or fixes something.
Think of someone who 'repairs' ('mend') things — the '-er' just means a person. A mender is someone who fixes things.
