Pronunciation

  • IPA: /daɪm/[1]

Etymology

It is inherited from Middle English dime (“tenth part, tithe”),[2][3][4][5] borrowed from Old French disme, dime (“tenth part”),[2][3][4][5][6] from Latin decima (“tenth part”), short for decima pars, the feminine of decimus (“tenth”),[2][3][4][5][7] from decem (“ten”) (see ten).[2][3][5][8] The root is Proto-Indo-European *dekm- (“ten”).[4]

Earliest recorded meaning

A tenth part, a tithe paid to the church or to a ruler (about 1377 in the OED; about 1378 in Barnhart).[9][3][10]

Semantic evolution

In 1786 the old word was chosen as the name of the United States coin worth ten cents, a tenth of a dollar.[3][4][9][11] Bartlett (1848) notes that the term was then in common use in the South and West, while in the East and North older names for Spanish coins persisted.[12] A dime novel, a cheap sensational novel, is recorded from 1859.[9][11] The phrase a dime a dozen, almost worthless, dates from 1930.[9][4] In drug slang a dime is ten dollars' worth of a drug,[13][5] and the verb to dime, to inform on someone, from the cost of a pay-phone call, is from the 1960s.[4][13]
