*angraz^¹

Probably from Proto-Indo-European *h₂enk-ró-s, a *-ró- derivative of the root *h₂enk-. Kroonen (2013: 28) compares Latin ancrae < PIE *h₂enk-reh₂-, a closely corresponding feminine r-formation. The underlying root is also represented by Ancient Greek ἄγκος (ánkos) and Sanskrit अङ्कस् (aṅkas), formally s-stem derivatives of *h₂enk- and good evidence for the semantic development from ‘bend, hollow’ to a hollow or low-lying piece of ground (Beekes 2010: 12–13, s.v. ἀγκύλος c)). Kroonen nevertheless allows an alternative reconstruction *angaza- < *h₂enk-os-o-, a thematicized s-stem based especially on the comparison with Greek ἄγκος (ánkos)(Kroonen 2013: 28). See also *angijō, possibly another Germanic derivative of *h₂enk-.
