despair: [14] Etymologically, despair is literally ‘lack of hope’. The word comes via Old French desperer from Latin dēspērāre, a compound verb formed from the prefix dē-, denoting reversal, and spērāre, a derivative of the noun spēs ‘hope’. Its past participle, dēspērātus, produced English desperate [15], from which desperado is a 17th-century mock-Spanish coinage.
