critic
nounA person skilled in judging of the merit of literary works; one who is able to discern and distinguish the beauties and faults of writing. In a more general sense, a person skilled in judging with propriety of any combination of objects, or of any work of art; and particularly of what are denominated the Fine Arts. A critic is one who, from experience, knowledge, habit or taste, can perceive the difference between propriety and impropriety, in objects or works presented to his view; between the natural and unnatural; the high and the low, or lofty and mean; the congruous and incongruous; the correct and incorrect, according to the established rules of the art.
