*ankijǭ

From Proto-Indo-European *h₂eng-yéh₂, from *h₂eng- (Kroonen 2013: 29, s.v. *ankjōn-) with the -i- from Siever's Law due to the heavy root. The weak ōn-stem inflection is probably secondary within Germanic, where jōn-stems formed a subtype of the productive feminine ōn-stems and inherited feminine vowel stems were readily transferred to this declension (Fulk 2018: 171–72). Particularly close is Vedic Sanskrit अङ्ग (áṅga); related formations include Sanskrit अङ्गुरि (aṅgúri) and Latin angulus, while Ancient Greek ἀγκών (ankṓn) belongs to the closely related *h₂enk- root (Beekes 2010: 12–13, s.v. ἀγκύλος; de Vaan 2008: 42–43; Kroonen 2013: 28–29, s.vv. *angan-, *ankjōn-; Kümmel 2016: 223; Rix et al. 2001: 268) . The exact preform is not entirely secure: *h₂eng- may represent a voiced variant beside *h₂enk-, and Kümmel (2016: 223) suggests that the Germanic *ank- forms may continue an inherited root variant represented directly by Vedic अङ्ग (áṅga) rather than simply belonging to the *h₂enk- group.
