The object agreement marker in all languages where it exists bears a significant relationship to some pronouns of that language which is both formal and semantic, in that the object agreement marker is always significantly similar in phonological form to a personal pronoun and can always be used to signify by itself the meaning of some personal pronominal object complement of the verb.
Standardized
An object agreement marker cannot be formally and semantically entirely distinct from a personal pronoun (in its object form).
