the.com/trespasser

means Someone who enters another person's property or land without permission or right to be there.

from From French 'trespasser' — 'trans' (across) plus 'passer' (to pass) — literally 'to pass across or beyond.' It first meant any transgression or sin in general, the sense you still hear in the old prayer 'forgive us our trespasses,' before narrowing over time to its modern, more literal meaning: crossing a boundary you had no right to cross.
