Tra falsafa e linguistica: Indoeuropeo *es e pronome separante arabo in Abū Naṣr al-Fārābī.

This contribution aims to discuss some passages by the philosopher Abū Naṣr al-Fārābī concerning the function of the so-called separated pronoun in nominal predicate sentences in Arabic. Through a comparative approach in his Kitāb al-urūf between Arabic, Greek and Persian, al-Fārābī gives an original interpretation of the role of this pronoun in Arabic, markedly different from that given by Arab grammarians.
