These words are closely related in meaning; they are derived from the same Latin word meaning "friendly." Amiable implies sweetness of temper, kindheartedness, or good-natured obligingness. Amicable has somewhat similar meanings but stresses the idea of being at peace, not disposed to quarrel."Mr. Jacks is a kindly and amiable employer." "All of my fellow employees are amicable."
