Note that the causativizer is ma-, if the verb root has a front or low vowel and mo-, if it has a nonfront or high vowel.Typically, the above have a cause + happen configuration so that causativization is co-extensive with transitivization. There is, however, a limited class of the transitivized verbs,
38.  jü ‘be big’ (intr.)   ma-jü ‘be as big as’ (tr.)’
Presumably all causatives are transitives ipso facto. But Mao has atleast one morphological causative verb which, on overt evidence, is not transitive; the verb is mo-kro ‘cause to go/up’ from kro’ go/come up’
39.  kheto mo-kro-e ‘(the) cooked rice is coming/going up     having been caused to come/go up’
3.4.3.2.	The Syntactic Causative
The syntactic causative has three sub-classes : a. the direct object being either subject or not subject to morphological causativization. b. the verb so ‘to do’ being preposed to the intrasitive verb root and c. the verb pi ‘to give’ being postposed to the intrasitive verb root.
