Etymology

Origin of trespass

First recorded in 1250–1300; (noun) Middle English trespas “transgression, offense,” from Old French, derivative of trespasser, equivalent to tres- (from Latin trāns- trans- ) + passer “to pass” ( see pass); (verb) Middle English trespassen, derivative of the noun

Explanation

To trespass is to illegally enter someone's property or overstep your bounds in another way. Have you ever seen a "No trespassing" sign? If so, you probably know it means "Keep out" and that trespassing is to go somewhere unlawfully. If you break into a store that's closed or enter a stranger's yard, you're trespassing and could be arrested. Also, trespassing refer to other types of stepping over boundaries. If you lie to a friend, that's a type of trespassing. Taking advantage of someone is trespassing. Both kinds of trespassing are violations.
