(By Alena Witzlack-Makarevich): "This question concerns languages which can index the person of an argument (S, A or P) somewhere in the clause (i.e. either on the verb or by clitics). The question asks whether person categories are not distinguished under certain circumstances. In order for there to be neutralization, there needs to be something to ‘neutralize’ to begin with, i.e. languages without person indexing should be coded 0 for this feature. All person categories should be neutralized for the language to be coded as 1. Do not consider phonologically independent pronouns for this question. Consider only independent clauses. Consider only the moods which allow all person categories of the language to be expressed (that is, ignore imperatives, jussives, etc.)
