Pronunciation

  • US: /ˈtændəm/[1]

Etymology

It is borrowed from Latin tandem (“at length, at last”), used as a joke,[2][3][4][5] applied in English to two horses harnessed "at length", one in front of the other.[5][6][1] The Latin adverb is formed from tam (“so, so much”) and the demonstrative suffix -dem,[4][7][3] and Etymonline and Klein trace tam to the Indo-European demonstrative root Proto-Indo-European *to-.[3][8][9] The Century Dictionary thought the pun probably arose at the universities,[3] and Skeat called it a university joke.[10] Merriam-Webster's “Word Histories” notes that the punster is unknown, but that the Latin word would be known to any student of the language.[5]

Earliest recorded meaning

A two-wheeled carriage drawn by two horses harnessed one before the other: 1785, in Grose's Classical Dictionary of the Vulgar Tongue.[2][5][4] Dictionary.com dates the word to 1735–45.[11]

Semantic evolution

The word soon lost its slang character and became the ordinary name for such a carriage.[5] By 1795 it also meant the pair of horses itself and was used as an adverb, "one behind the other";[2][4] the adjective is recorded from 1801.[3][4] In the course of the 19th century it came to describe any arrangement of people or things one behind another,[5][2] and in 1884 it was transferred to a bicycle for two riders, probably short for tandem bicycle.[4][6][2] Ayto dates the general sense of acting together to the early 20th century,[6] and the phrase in tandem, together or in partnership, is recorded from 1930.[2][12] The word was also used of airplanes with one set of wings in front of another.[5]
