(n.) The neutral compound formed by the union of an acid and a base; thus, sulphuric acid and iron form the salt sulphate of iron or green vitriol.
(n.) 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.
(n.) Any mineral salt used as an aperient or cathartic, especially Epsom salts, Rochelle salt, or Glauber's salt.
(n.) Marshes flooded by the tide.
(n.) Of or relating to salt; abounding in, or containing, salt; prepared or preserved with, or tasting of, salt; salted; as, salt beef; salt water.
(n.) Overflowed with, or growing in, salt water; as, a salt marsh; salt grass.
(n.) Fig.: Bitter; sharp; pungent.
(n.) Fig.: Salacious; lecherous; lustful.
