Ingratiating → It is formed from "in-" (meaning into or in) and "gratia" (from Latin, meaning favor or grace) and the suffix "-ing" (indicating the action or process). The word describes the action of bringing oneself into favor or grace with someone, often through flattery or charm.
Think of 'bringing oneself into favor' ('in-' means into, and 'gratia' means favor) — that's why ingratiating means trying to win someone's approval.
