/ë/ is inserted (1) between /h/ and /m/ of the MP suffix and between /m/ and /n/.
The first insertion is rounded to /ù/ before /m/.
The first person plural suffix /-nan/ is realized as /-na/ in final position.
NOTE: the underlying structure of this form is the same as that of the form glossed "we see you (sg.)." It is not clear that all speakers understood the different treatment of these forms as constituting different meanings.
