ferry (v.)
Old English ferian "to carry, convey, bring, transport," from Proto-Germanic *farjan "to ferry" (cognates: Old Frisian feria "carry, transport," Old Norse ferja "to pass over, to ferry," Gothic farjan "travel by boat"), from PIE root *per- (2) "to lead, pass over" (see port (n.1)). Related to fare (v.). Related: Ferried; ferries; ferrying.
ferry (n.)
early 15c., "a passage over a river," from Old Norse ferju- "passage across water," ultimately from the same Germanic root as ferry (v.). The modern noun (1580s) is a shortening of ferry boat (mid-15c.).
