What is the meaning of 'improbus'?

The word 'improbus' in Latin conveys a sense of moral failing or undesirable behavior, translating to “cruel,” “bad,” or “disloyal.” The root of the term reflects a negative connotation, often associated with someone who acts unethically or immorally. In a broader context, this word has been used in various Latin literature, including Cicero's works, to describe individuals who show a lack of virtue or decency.

This understanding aligns with the negative qualities implied by the word and reinforces its usage in depicting characters or actions that are fundamentally flawed or wicked. Other options suggest positive or neutral traits that do not match the inherent meaning of 'improbus,' thus affirming that the correct choice relates specifically to the negative characteristics denoted by the term.
