Insinuator → It is formed from "in-" (meaning into) and "sinuare" (meaning to curve or bend). The word describes someone who subtly introduces or suggests something, often in a sly or indirect manner.
Think of someone who is 'bending' or 'curving' their way 'into' a conversation to suggest something subtly — that's what an insinuator does.
