Encroach is formed from "en-" (meaning to cause to) and "croche" (from Old French *crocher*, meaning to hook or seize). The word describes the act of gradually seizing or intruding upon someone else's space or rights, as if hooking onto them.
Think of the idea of 'causing to hook' onto something, which helps you remember that to encroach means to gradually intrude or seize upon someone else's territory.
