Ultimate origin

Pronunciation

  • UK: /ɪntɹəˈviːnəs/[1]

Etymology

It is formed from English intra- + venous,[2][3][4] the second part ultimately from Latin vēna (“vein”).[5][6][7] The OED analyses it as intra- with the Latin noun directly, comparing venous,[5] and Barnhart as intra- with vēnōsus, from vēna;[7] Merriam-Webster counts it as International Scientific Vocabulary.[2] The OED compares French intraveineux, recorded in Littré's supplement.[5]

Earliest recorded meaning

Existing or taking place within a vein or the veins: 1849–52, in Todd's Cyclopædia of Anatomy and Physiology.[5] Barnhart dates it to 1847–49, and Etymonline to 1845.[7][6]

Semantic evolution

The adjective has kept its first sense, and is used especially of injections and feeding into a vein.[2][8] The noun, an intravenous injection or feeding, is recorded from 1960, in a science fiction story by J. G. Ballard;[5][7] in this use the word is often abbreviated IV.[8] The adverb intravenously is from the late 19th century.[3]
