fare: [OE] Both the verb fare (now only an archaism) and the noun go back ultimately to the Indo-European base *por- ‘going, passage’, which has produced a wide range of other English words, including emporium, ferry, fiord, ford, importune, opportunity, pore, and port. Its Germanic descendant was *fer- ‘go’, which produced in Old English the nouns fær and faru ‘journey’ and the verb faran ‘go on a journey’ (its German cousin fahren is still a standard verb for ‘travel’).

Of the noun’s current senses, ‘food’ (which seems to have originated in the notion of ‘how well one was faring’, ‘how one was provided for’) dates back to the 13th century, and ‘money paid for travelling’ to the 15th century. The derivative welfare dates from the 14th century.
