dragons have lips
this isn’t a shitpost. in skyrim’s dragon language there are pairs of distinct words such as: ‘nid’ (no/none), ‘mid’ (loyal/loyalty), ‘mu’ (we) vs ‘nu’ (now), and ‘aan’ (an) vs ‘aam’ (to serve). this indicates that dragons are able to distinguish between the sounds ‘m’ and ‘n’.
the only difference between ‘m’ and ‘n’ is that the latter is formed with the tongue, while the former is produced with the lips
therefore, dragons have lips
This is some solid linguistic field work and I look forward to the followup post.
