Correct spelling, explanation: trespass is a Middle English word, which has its roots in the Latin word transpassare. The first language that took this word from Latin was French, in which it looked as trespas and trespasser. After that, English adopted the word trespass in the form we know today.

Definition of trespass:
1. verb – to enter somebody’s land when you are not permitted to do so;
It wasn’t my intention to trespass on your land – I was sure it is a public area.
2. noun (old use) – not moral, a sin,
Murdering a person is probably the most serious trespass.

Trespass word family:
Other words that belong to the same family as trespass are trespassing (the act of entering a forbidden place), and trespasser (a person who enters somebody’s land without permission).
In most states of America, trespassing is considered to be a serious crime.
A trespasser who dares to enter my land may get shot.

Incorrect spelling, explanation: it is worth noticing that the word trespass features a double -s letter only at the end of the word while in the middle of the word there is only a single s. Users of English, however, get confused about that and a common mistake is to spell the word trespass as tresspass, which is wrong.
