The IC prefix metathesizes with root-initial /m/, dropping /y/ and realizing /ea/ as /e/, a strong vowel, which is laxed in a closed syllable.
The first /à/ of the root is dropped following a strong vowel.
/ë/ of the suffix is rounded to /ù/ after /m/.
See also /mèhmalamùnt/, same meaning but derived from different treatment of underlying form.
