A more thorough explanation:

Definition: Indefensus (in-də-fen-səs) is a Latin term that means "undefended." In Roman law, it refers to a person who fails to make a defense or plea to an action. The term later acquired a similar meaning in English law.

Example: If someone is sued in court and they do not respond or make a defense, they are considered indefensus. This means that they have not presented any arguments or evidence to support their case, and the court may rule against them by default.

Another example: In criminal cases, if a defendant does not provide a defense or plea, they may be considered indefensus. This could result in a guilty verdict and a harsher sentence.

These examples illustrate how the term indefensus is used in legal contexts to describe a person who fails to defend themselves or make a plea in court. It is important for individuals to present a defense or plea in order to have a fair trial and protect their rights.
