Cf. {Sal}, {Salad}, {Salary}, {Saline}, {Sauce}, {Sausage}.] 1. The chloride of sodium, a substance used for seasoning food, for the preservation of meat, etc. It is found native in the earth, and is also produced, by evaporation and crystallization, from sea water and other water impregnated with saline particles. [1913 Webster]

2. Hence, flavor; taste; savor; smack; seasoning. [1913 Webster]

In the case of diacid and triacid bases, and of dibasic and tribasic acids, the mutual neutralization may vary in degree, producing respectively basic, neutral, or acid salts. See Phrases below. [1913 Webster]

7. Fig.: That which preserves from corruption or error; that which purifies; a corrective; an antiseptic; also, an allowance or deduction; as, his statements must be taken with a grain of salt. [1913 Webster]

See {Saltfoot}. [1913 Webster]
