Syn. -- Grief; concern; sorrow; lamentation; repentance; penitence; self-condemnation. -- Regret, Remorse, Compunction, Contrition, Repentance. Regret does not carry with it the energy of remorse, the sting of compunction, the sacredness of contrition, or the practical character of repentance. We even apply the term regret to circumstance over which we have had no control, as the absence of friends or their loss. When connected with ourselves, it relates rather to unwise acts than to wrong or sinful ones. C. J. Smith.
