Forms

transfuser[1] Middle French had the adjective transfus (“transfused”) (1548) and the verb transfundre (“to pass on, transmit”) (1542).[2]

Etymology

It is from Middle French transfus (“transfused”), with the verb ending -er.[2][3][4] That adjective is the past participle of transfundre, borrowed from Latin transfundō (“to pour from one vessel into another”), figuratively “to pour out on, spread”.[2][5] The Grand Robert, the Petit Robert and Littré derive the verb directly from the supine of the Latin verb, formed from trāns- (“beyond”) and fundō (“to pour”).[6][7][8]

Earliest recorded meaning

It is first recorded on 6 February 1668 in the Journal des savants, which reports a spaniel into which sheep's blood had been transfused.[2]

Semantic evolution

The verb and the noun transfuseur (1667, then “supporter of transfusion”) date from the time when blood transfusion was first tried; because the practice was then forbidden, the words only spread in their medical sense in the 19th century.[3][2] From 1701 the verb also meant to pour a liquid from one vessel into another, a sense now dated.[2][4] Balzac used it figuratively in 1833 for passing qualities or gifts on to others, and Chateaubriand in 1848 of a dialect whose flavour cannot be carried into another language.[2][9] The participle transfusé became a noun in 1882 for the receiver of blood, opposed to the donneur.[2][3][7]
