Word Origin for trunk

C15: from Old French tronc, from Latin truncus, from truncus (adj) lopped
Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William Collins Sons & Co. Ltd. 1979, 1986 © HarperCollins Publishers 1998, 2000, 2003, 2005, 2006, 2007, 2009, 2012

Word Origin and History for trunker



mid-15c., "box, case," from Old French tronc "alms box in a church" (12c.), also "trunk of a tree, trunk of the human body," from Latin truncus, originally "mutilated, cut off." The meaning "box, case" is likely to be from the notion of the body as the "case" of the organs. English acquired the other two senses of the Old French in late 15c.: "main stem of a tree" and "torso of a human body." The sense of "luggage compartment of a motor vehicle" is from 1930. The use in reference to an elephant's snout is from 1560s, perhaps from confusion with trump (short for trumpet). Railroad trunk line is attested from 1843; telephone version is from 1889.
