A unified analysis of polar particles in Farsi

Polar Response Particles (PRPs) have been widely studied in the literature, discussing essence of their ambiguity polarity and (dis)agreement reading sys- tems (Pope 1976) what affects preference. In languages like English Farsi, which same particles satisfy both readings, PRPs are ambiguous response to negative initiatives (including questions assertions). on other hand, not only used assertive responses polar initiatives, but they also appear interrogatives tag alternative questions. this paper, I propose a unified analysis Farsi forms. My is based feature marking account (Roelofsen Farkas 2015), lexical that can benefit for interrogative forms too. Moreover, claim bias affect variation cases, sense stronger antecedent higher preference over comparison reading.
