(sāl) noun
1. The act of selling; the exchange or transfer of property for money or its equivalent.
2. An auction or selling–off at bargain prices.
3. Opportunity of selling; demand by purchasers; market: Stocks find no sale.
—for sale (or on sale) Offered or ready for sale. ♦ Homophone: sail. [OE sala, prob. <ON] Synonyms: bargain, barter, change, deal, exchange, trade. A bargain is strictly an agreement or contract to buy and sell; (see CONTRACT) but the word is often used to denote the entire transaction and also the thing sold or purchased. Change and exchange are words of wider signification, applying only incidentally to the transfer of property or value; a change secures something different in any way or by any means; an exchange secures something as an equivalent or return, but not necessarily as payment for what is given. Barter is the exchange of one commodity, generally a portable one, for another. Trade in the broad sense may apply to vast businesses (as the book trade), but as denoting a single transaction is used chiefly in regard to things of moderate value, when it becomes nearly synonymous with barter. Sale is commonly limited to the transfer of property for money, or for something estimated at a money value or considered as equivalent to so much money. A deal in the political sense is a bargain, substitution, or transfer for the benefit of certain persons or parties against all others; as, The nomination was the result of a deal; in business it may have a similar meaning, but it frequently signifies simply a sale or exchange, a dealing.
