There is also a morphological causative in Chatino, expressed by the causative prefix /x-/, /xa-/, /y/, or by the palatalization of the first consonant. The choice of prefix appears to be partially determined by the first consonant of the verb, though there are some irregular cases. The prefix /x/ occurs before some roots that start with one of the following consonants: /c, qu, ty/ or with the vowels /u,a/, e.g.
|catá chcu||'bathe (reflexive)'||xcatá ji'i||'bathe (transitive)'|
|quityi||'dry (reflexive)'||xquityi ji'i||'dry (tr)'|
|ndyu'u||'is alive'||nxtyu'u ji'i||'waken'|
|ndyubi'||'is put out'||nxubi'||'put out'|
The prefix /xa/ is put before certain roots that begin with /t/, e.g.
|nduu||'is stopping'||nxatuu||'to stop something'|
Palatalization occurs in some roots that begin with /t/, e.g.
taa 'will give' tyaa 'will pay'
