Universal 409: ((person marker (possessee) = person marker (verb(non-indicative))) ⇒ ((person marker (possessee) = person marker (verb (indicative)))
Original
If person marking is phonologically identical for possessed nouns and verbs of non-indicative moods (imperative, interrogative, optative), this will also be the case in the indicative mood.
Standardized
IF person marking is phonologically identical for possessed nouns and verbs of non-indicative moods (imperative, interrogative, optative), THEN this will also be true in the indicative mood.
Doesn’t necessarily hold for all persons.
