A person who helps to arrange marriages or romantic relationships between people.

Matchmaker → It is formed from "match" (from Old English *mæcca*, meaning a pair or a mate) and "maker" (from Old English *macian*, meaning to make or create). A matchmaker is someone who creates or brings together pairs or mates, typically in the context of romantic relationships.
Think of someone who 'creates' ('maker') a 'pair' ('match') — that's why a matchmaker is someone who brings couples together.
