synonyms ART, SKILL, CUNNING, ARTIFICE, CRAFT mean the faculty of executing well what one has devised. ART implies a personal, unanalyzable creative power (the art of choosing the right word). SKILL stresses technical knowledge and proficiency (the skill of a glassblower). CUNNING suggests ingenuity and subtlety in devising, inventing, or executing (a mystery plotted with great cunning). ARTIFICE suggests technical skill especially in imitating things in nature (believed realism in film could be achieved only by artifice). CRAFT may imply expertness in workmanship (the craft of a master goldsmith).
