atrabilious

An atrabilious monk in his garret vented his spleen with more than usual acrimony, and the world applauded.

He now sees what a regard they have for the health of the atrabilious South Americans.

The country has its eye on that knot of atrabilious Liberals whose voice is that of Jacob, but whose hands are the hands of Esau.

After his conversion he made amends, though he was always the atrabilious faultfinder.
