The varients presented in the note below are arranged according to their frequency of occurrence in the survey data-from most frequent to least frequent.
Genitive 3rd person singular

The genitive is an adnominal case whose core function is to mark a nominal whose referent (possessor) is connected by a possessive relation to the individual expressed by the phrase within which the genitive phrase is embedded (possessum). (Lander 2008:58). Hence genitive construction is a kind of possessive construction. For example, in the standard Marathi sentence, he rəmešcə ɡʰər ahe (this ramesh-of home is; ‘This is Ramesh’s home’) the inflection [-cə] marks the possessive relation between the possessor Ramesh (proper name) and the possessum home ‘house’
