Causing loss of hope

Usage examples of demoralising.

Nek and the destruction of the northern portion of the railway, or a successful raid or invasion such as they have reason to believe is contemplated, would produce a most demoralising effect on the natives and on the loyal Europeans in the colony, and would afford great encouragement to the Boers and to their sympathisers in the colonies, who, although armed and prepared, will probably keep quiet unless they receive some encouragement of the sort.

It was a demoralising tactic which that jockey often used against horses he thought frightenable, but I was in no mood to be overcrowded by him or by anybody, and I was conscious, as too often recently, of ruthlessness and rage inside and of repressed desperation bursting out.
