Legal Definitions - penetration

Definition: Penetration is the act of entering or passing through something.

Example 1: In criminal law, penetration refers to the entry of the penis or some other part of the body or a foreign object into the vagina or other bodily orifice. This is considered a sexual offense and is also known as intromission.

Example 2: Penetration can also refer to the depth reached by a bullet or other projectile in something against which the projectile is fired. For instance, if a bullet penetrates a wall, it means that it has passed through the wall and entered the other side.
