A more thorough explanation:

Manu forti (man-yoo for-tI) is a Latin term that means "with strong hand." It was commonly used in old writs of trespass to allege forcible entry, as in manu forti et cum multitudine gentium ("with strong hand and multitude of people").

An example of the use of manu forti would be in a legal case where someone was accused of breaking into a property by using force. For instance, if someone broke into a house by breaking down the door, it could be said that they entered manu forti.

Another example would be if a group of people forcefully entered a building, such as a government office, to protest. In this case, it could be said that they entered manu forti et cum multitudine gentium.

The examples illustrate the definition of manu forti by showing how it was used in legal cases to describe a situation where someone entered a property or building by using force. The term emphasizes the use of physical strength to gain entry, rather than peaceful means. The addition of "et cum multitudine gentium" in the second example highlights the fact that the entry was not only forceful, but also involved a large group of people.
