Etymology

It is formed from English split + -er, an agent noun from the verb.^{[2][3][4][5][6]} The verb split is probably from a Low German source such as Middle Dutch splitten.^[3][4]

Earliest recorded meaning

A person employed in splitting fish: 1623, in Richard Whitbourne's Discourse on Newfoundland,^[2] the date Merriam-Webster Unabridged also gives.^[4] The general sense, a person or thing that splits or cleaves, is first recorded in 1648, in Hexham's Dutch–English dictionary;^[2] Etymonline dates it to the 1640s.^[3]

Semantic evolution

The figurative sense, someone who makes fine or subtle distinctions, appears in 1699 in the New Dictionary of the Canting Crew,^[2] the phrase to split hairs being implied from the 1670s.^[3] Johnson (1755) defined the word simply as "one who splits", quoting Swift.^[7] In 1887 Darwin opposed splitters to lumpers: in biological classification, those who divide species finely against those who group them broadly,^[3][2][5] a sense later extended to analysis in general.^[5] In Australia from 1841 a splitter was a wood-cutter who split timber for posts and rails.^[2][5] Slang uses include a splitting headache (1860, in Thackeray),^[2][5] a first-rate hunt in hunting slang (1843),^[2][5] and, in 1840s London underworld slang, an outstanding person.^[8] From 1895 a splitter was also someone who split the vote.^[2] Since the mid 19th century it has also been a machine or device that splits something,^[5] later such as one that sends a current or signal along several routes,^[5] or an auxiliary set of gears between the ratios of a main gearbox (1963).^[2][5]
