Wanhope

Wanhope: a fine English word, suggesting unhope of Langland's story of the cats and the mice, and described in Ipotis,[…]

If[…]such good old English words as inwit and wanhope should be rehabilitated (and they have been pushing up their heads for thirty years), we should gain a great deal. (Collected essays, 1928, III.68)

Both despair and wanhope are generally defined as a complete loss or lack of hope and being overcome by sense of futility or defeat.
