IPA: /ˈpætʃər/
KK: /ˈpætʃər/
A person who repairs or fixes something, often by adding a patch or a piece to cover a hole or damage.
The patcher quickly fixed the hole in the wall with a piece of drywall.
Patcher → It is formed from "patch" (from Middle English *pacche*, meaning a piece of material used to cover a hole) and "-er" (meaning a person who). A patcher is a person who covers or repairs holes with patches.
Think of someone who uses a piece of material ('patch') to cover or fix something, and the '-er' indicates that this person is doing the action.
