A more thorough explanation:

Definition: The act of providing a place to stay, shelter, or protection to a person, especially a criminal or someone who is in the country illegally.

Example 1: John was arrested for harboring his friend who was wanted by the police for robbery.

Example 2: The company was fined for harboring undocumented workers in their factory.

These examples illustrate how harboring involves providing a place to stay or protection to someone who is either a criminal or in the country illegally. In both examples, the individuals were knowingly providing shelter to someone who was breaking the law. Harboring is a serious offense and can result in legal consequences for those who engage in it.
