Expensive, costly, dear, high-priced apply to something that is high in price. Expensive is applied to whatever entails considerable expense; it suggests a price more than the average person would normally be able to pay or a price paid only for something special: an expensive automobile. Costly implies that the price is a large sum, usually because of the fineness, preciousness, etc., of the object: a costly jewel. Dear is commonly applied in England to something that is selling beyond its usual or just price. In the U.S., high-priced is the usual equivalent.
