Which word refers to a feeling of guilt or remorse?

The term that specifically denotes a feeling of guilt or remorse is "contrite." When someone feels contrite, it conveys a deep sense of regret and sorrow for having done something wrong. This term is often associated with a desire to make amends or seek forgiveness, highlighting the emotional weight that accompanies the feeling of guilt.

While "regretful," "apologetic," and "pained" can relate to feelings of remorse or disappointment, they do not capture the same depth of emotional acknowledgment and self-reflection that "contrite" does. "Regretful" indicates a sense of wishing something had happened differently but lacks the depth of feeling guilty. "Apologetic" implies a readiness to apologize but doesn't specifically denote guilt itself. "Pained" refers to a general feeling of distress or anguish, which may not necessarily be tied to guilt. Therefore, "contrite" stands out as the most precise descriptor for someone experiencing guilt or remorse.
