IPA: /ˈrɪərər/
KK: /ˈrɪrər/
A person who takes care of and raises children or animals.

Rearer → It is formed from "rear" (from Old English *herian*, meaning to raise or elevate) and "-er" (meaning a person who). A rearer is a person who raises or brings up something, often used in the context of raising children or animals.
Think of someone who 'raises' ('rear') something, like children or animals, and the '-er' just means a person. A rearer is someone who brings up or nurtures.
