Nourisher → It is formed from "nourish" (from Old French *nourrir*, meaning to feed or nurture) and "-er" (meaning a person who). A nourisher is a person who feeds or nurtures others.
Think of someone who 'feeds' ('nourish') others — the '-er' just means a person. A nourisher is someone who provides nourishment.
