|A. camme=A=O||A eat, consume, intake O|
Camme is derived from casa ‘belly’ plus the obsolete particle me ‘into’, so ‘into the belly’. Thus, it is entirely appropriate that camme means ‘eat O’ when O is a class III food noun.
One peculiarity of Xunumi-Wudu verb phrases is that they can include a noun preceding the verb to describe an instrument or manner. Not all verbs do this, but camme certainly does. Camme can use body parts such as doŋi ‘eye’, sada ‘ear’, and giŋi ‘nose’ as incorporated manner nouns, and then means to deliberately intake via the noun. So doŋi-camme ‘deliberately look at/watch O’, sada-camme ‘deliberately listen to/for O’, giŋi-camme ‘deliberately sniff/taste O’. With all these verbs, the subject is the perceiver and the object is the sight, sound, smell, or taste perceived.
