Hogg, Richard; Fulk, R. D. (1992), A Grammar of Old English, volume 1: Phonology, Oxford: Blackwell, →ISBN, page 256:When a velar consonant occurred finally after /i/ or /j/ but preceded directly by a nasal, then palatalization still occurred. [...] drinċ ‘drink’ imp., þinġ ‘thing’, hrinġ ‘ring’.

R. D. Fulk (2014), An Introductory Grammar of Old English, published 2020, page 104:

As for g after n, this is affricated, like c, only after i or a vowel that has undergone front mutation, as with nom.-acc. sg. þinġ ‘thing’ and menġan ‘mingle’ (from *mangjan); but affrication after -in- is prevented by a following back vowel: cf. singan. Presumably affrication also failed in nom.-acc. pl. þing < *þingu, but it may have been restored by analogy, though this cannot be known for certain.
