Origin & History of “trunk”
Trunk came via Old French tronc from Latin truncus (source also of English trench and truncate). this denoted ‘something with its protruding parts torn off’, hence ‘something regarded separately from its protruding parts’ – the stem of a tree without its branches, or a body without its limbs. The application of the English word to an ‘elephant’s proboscis’, which dates from the 16th century, apparently arose from some confusion with trump ‘trumpet’.
