Complacence
COMPLACENCE,
COMPLACENCY, noun
1. Pleasure; satisfaction; gratification. It is more than approbation, and less than delight or joy.
Other proclaim the infirmities of a great man with satisfaction and complacency, if they discover none of the like in themselves.
2. The cause of pleasure or joy.
3. Complaisance; civility; softness of manners; deportment and address that afford pleasure.
Complacency, and truth, and manly sweetness,
Dwell ever on his tongue, and smooth his thoughts.
In the latter sense, complaisance, from the French, is now used. [See Complaisance.]
