desperation (n.)

late 14c., desperacioun, "hopelessness, lack or loss of hope" (especially in God's mercy), a sense now obsolete; c. 1400, "a desperate state of mind," from Old French désperacion or directly from Latin desperationem (nominative desperatio) "despair, hopelessness," noun of action from past-participle stem of desperare "to despair, to lose all hope," from de "without" (see de-) + sperare "to hope," from spes "hope" (from PIE root *spes- "prosperity;" see speed (n.)).
