A more thorough explanation:

Explanation: Pro Defendente is a Latin term that means "for the defendant." It is often used in legal documents to indicate that a particular argument or action is being taken on behalf of the defendant in a case.

Example: In a court case, a lawyer might argue "pro def" to indicate that they are making a statement in defense of their client.

Another example: A group of supporters might hold up signs that say "pro def" outside of a courthouse to show their support for the defendant.

Illustration: These examples show how "pro def" is used to indicate support for the defendant in a legal case. It is a shorthand way of saying that a particular argument or action is being taken on behalf of the defendant, and it is often used in legal documents and proceedings.
