A more thorough explanation:

Definition: A trespasser is someone who enters someone else's property without permission or legal right to do so.

In tort law, a landowner is not responsible for injuries caused to a trespasser unless the landowner intentionally caused harm or was grossly negligent. This means that if someone enters your property without permission and gets hurt, you are not liable for their injuries.

Examples:

• If someone jumps over your fence and enters your backyard without your permission, they are considered a trespasser.
• If a person enters a construction site without permission, they are considered a trespasser.
• If a hiker accidentally wanders onto private property without realizing it, they are still considered a trespasser.

These examples illustrate the definition of a trespasser because in each case, the person entered someone else's property without permission or legal right to do so. As a result, they are considered trespassers and may be subject to legal consequences.
