"Interact" is a verb that means to communicate with or react to one another. It's not considered a compound word, but it does have the prefix "inter-," which means mutually or reciprocally, and the word "act" attached to it, implying that the actions are reciprocal. Ex: I haven't interacted with people for a while since I've been sick. Ex: When the chemicals react with each other, the temperature rises.
