Dan. initial nasals vanished before stops; [{mnŋ}{bdg}-] > [ø{bdg}-]
According to the Comparative Tables, initial combinations of nasals with voiced stops reduced to simple voiced stops (PE19/20). There are two examples of this development in The Etymologies: Dan. golda < ᴹ√ÑGOLOD (Ety/ÑGOLOD) and Oss. Dior < ᴹ✶ndeuro (EtyAC/NDEW), though Tolkien later decided this second example was actually Ilkorin. There were similar changes in Noldorin and Ilkorin. In the case of the cluster [ŋgw-], the resulting [gw-] further reduced to [w-], indicating that the loss of the nasal probably happened before initial [g] was lost before [w].
