Partial excuses are explanations or justifications for someone's behavior or actions that do not entirely absolve them of blame or responsibility. Synonyms for this phrase might include mitigating circumstances, extenuating factors, or partial defenses. These terms all suggest that there are reasons that partially explain someone's actions, but that they do not fully excuse them. Other possible synonyms might include minor absolutions, lesser justifications, or partial pardons. Regardless of the exact phrase used, the meaning remains the same: while partial excuses may provide some justification for behavior that might otherwise be seen as wrong, they do not entirely absolve someone of responsibility for their actions.
