/w/ metathesizes with /t/ and is absorbed by /u/.
/y/ is inserted as a transition sound between /i/ and /ë/.
/ë/ is inserted as a transition sound between /m/ and /n/.
The inserted sound is raised to /i/ before /n/ in a closed syllable.
Note: this form differs from /tuhwèpink/ only by the addition of an explicit possessive suffix; without the suffix one still assumes that a body belongs to someone.
