Racy, a. [Compar. Racier; superl. Raciest.]
Etymology: [From Race a tribe, family.]
1. Having a strong flavor indicating origin; of distinct characteristic taste; tasting of the soil; hence, fresh; rich. The racy wine, Late from the mellowing cask restored to light. Pope.
2. Hence: Exciting to the mental taste by a strong or distinctive character of thought or language; peculiar and piquant; fresh and lively. Our raciest, most idiomatic popular word. M. Arnold. Burn's English, though not so racy as his Scotch, is generally correct. H. Coleridge. The rich and racy humor of a natural converser fresh from the plow. Prof. Wilson.
Syn. -- Spicy; spirited; lively; smart; piquant. -- Racy, Spicy. Racy refers primarily to that peculiar flavor which certain wines are supposed to derive from the soil in which the grapes were grown; and hence we call a style or production racy when it "smacks of the soil," or has an uncommon degree of natural freshness and distinctiveness of thought and language. Spicy, when applied, has reference to a spirit and pungency added by art, seasoning the matter like a condiment. It does not, like racy, suggest native peculiarity. A spicy article in a magazine; a spicy retort. Racy in conversation; a racy remark. Rich, racy verses, in which we The soil from which they come, taste, smell, and see. Cowley.
Shades of meaning
Racy applies in the first instance to the pleasing flavor characteristic of certain wines, often attributed to the soil from which they come. Pungent denotes something sharply irritating to the organs of taste or smell, as pepper, vinegar, ammonia; piquant denotes a quality similar in kind to pungent but less in degree, stimulating and agreeable; pungent spices may be deftly compounded into a piquant sauce. As applied to literary products, racy refers to that which has a striking, vigorous, pleasing originality; spicy to that which is stimulating to the mental taste, as spice is to the physical; piquant and pungent in their figurative use keep very close to their literal sense.
