I have come across its use as a proper noun in an 1895 deed:
"...all that one piece of pasture lying at Whatling Went."
So I wondered if there is any evidence for the the use of 'went' as a common noun, as a back-formation from the verb. Otherwise, how would anyone have thought to use it in this name?
Intuitively it seems to have the meaning of a strip of land or track along which you go.
I can think of another jokingly inventive use of 'went' as a noun, as in "These days he has plenty of got up and went." But that's different.
