O.E. neahgebur (W.Saxon), nehebur (Anglian), from neah “near” (see nigh) + gebur “dweller,” related to bur “dwelling” (see bower). Common Gmc. compound (cf. Du. (na)bur, O.H.G. nahgibur, M.H.G. nachgebur, Ger. Nachbar). The verb is first attested in 1586.
you look up BOWER and find
O.E. bur “room, hut, dwelling, chamber,” from P.Gmc. *buraz (cf. O.N. bur “chamber,” Swed. bur “cage,” O.H.G. bur “dwelling, chamber,” Ger. Bauer “birdcage”), from base *bu- “to dwell,” from PIE base *bheue- “to be, exist, dwell” (see be). Modern spelling developed after mid-14c. Sense of “leafy arbor” (place closed in by trees) is first attested 1520s. Hence, too, Australia’s bower-bird (1847).

calipers. Borders, once described as from these
rocks to that old tree, flutter like broken string:
the rocks are scattered or stacked into walls;
the tree, lightning-struck or a floor somewhere.
Briers define our limits now, growing from dust
and sawdust. They guard heart with thorns,
tempt with sweet fruit. He said that every time
he played–close enough for country.
