Etymology

It is borrowed from French sulfate,[2][3][4] which Etymonline and Barnhart give as sulphate and Etymonline dates to 1787,[5][6] from New Latin sulphātum,[7] in the phrase sulphatum acidum,[5][6] formed from Latin sulphur (see sulfur),[5][6][4] and the chemical suffix -ate (see -ate).[2][5] Merriam-Webster takes the English spelling sulphate as an alteration of the French word under the influence of sulphur.[2]

Earliest recorded meaning

A salt of sulfuric acid: 1790, as sulphat, in Kerr's translation of Lavoisier.[5][6][8] Merriam-Webster dates the word to 1788.[2]

Semantic evolution

The word belongs to the chemical naming introduced with Lavoisier's new chemistry, which reached English through translations of his work.[5] Barnhart records the spelling sulphate in English from 1794 and sulfate from 1809.[6] Sulphate remains the standard British spelling,[5][9] while Collins calls sulfate the preferred American one.[9] The noun came to be used on its own for sodium sulfate (1879) and in compounds such as sulphate process, a way of making strong brown paper from wood pulp (1902).[8][3] A verb, to become or make sulfated, followed in 1888.[8][2] In drug slang sulphate is amphetamine sulphate.[9][10]
