Pronunciation

Etymology

It is borrowed from Latin ductus (“a leading, conduct, command”),[2][3][4][5] in medieval Latin also an aqueduct,[2][6][7] a noun of action formed from the past participle of dūcō (“to lead”),[3][5][8] from Proto-Indo-European *deuk- (“to lead”).[3][5] The Latin form ductus was itself once used in English.[2] The same verb gave conduct, deduce, introduce, produce and aqueduct.[8][9][10]

Earliest recorded meaning

Course, direction: 1650, in J. Bulwer's Anthropometamorphosis.[2][4] Etymonline dates it to the 1640s,[3] and Merriam-Webster gives 1654 for the sense "guidance".[11]

Semantic evolution

The abstract senses of leading, guidance and direction died out by the early 18th century.[2][7] The anatomical sense, a vessel carrying bodily fluids, came in 1667, in the Philosophical Transactions,[2][4][3] and was long used broadly, including blood vessels.[2] A conduit for water followed in 1713, in Pope;[2][3] later came an air pipe for ventilation (1884), a conduit for electric cable (1892) and a vessel in the tissue of plants (1858).[2][3] A duct was also a stroke traced in writing a letter, from 1699.[2][7] The verb, to convey through a duct, dates from 1936.[2][11]

Usage notes

Duct tape was originally duck tape (1894), strips of cotton duck cloth; the name passed to a plastic-coated adhesive tape used by American soldiers in the Second World War and became duct tape by 1958, perhaps because the tape was often used on air ducts.[3]
