*anhulō

From Proto-Indo-European *h₂énk-ul-eh₂, from root *h₂enk-, probably originally denoting a bent or looped object and hence a strap or thong (Beekes 2010: 12–13, s.v. ἀγκύλος; Derksen 2015: 56, s.v. anka; Kroonen 2013: 29; Ringe 2017: 124; Rix et al. 2001: 268). Ringe reconstructs the phonological preform as *h₂ánkulah₂ and notes that *anhulō beside *angulaz preserves an inherited accentual contrast: root accent in *h₂ánkulah₂ prevented Verner voicing of the fricative produced by Grimm’s Law (*k > *h), whereas suffixal accent in *h₂ankulós yielded *g in *angulaz (Ringe 2017: 124). Cognate with Ancient Greek ἀγκύλη (ankúlē) from the same feminine formation, and related to Lithuanian ánka, from the same PIE root (Beekes 2010: 12–13, s.v. ἀγκύλος; Derksen 2015: 56, s.v. anka; Kroonen 2013: 29).
