Phrynichus Arabius
Phrynichus Arabius (/ˈfrɪnɪkəs/; Ancient Greek: Φρύνιχος Ἀράβιος, lit. 'Phrynichus “the Arab”') or Phrynichus of Bithynia (Ancient Greek: Φρύνιχος ὁ Βιθυνός) was a grammarian of the Greek language who flourished in 2nd century Bithynia, writing works on proper Attic usage. His name is also transliterated as Phrynichos or Phrynikhos. His ethnic background is disputed, mainly between an Arab and Bithynian Greek descent.
