/ë/ is inserted as a transition sound (1) between /l/ and /h/ and (2) between /h/ and /m/ of the MP suffix.
The first of these insertions is raised to /u/.
/wa/ is realized as /o/, and /w/ is elided in final position after a vowel.
NOTE: The underlying form is the same as that glossed "I see you (three or more people)." It is not clear that all speakers understand the different phonological treatment as leading to a different meaning.
