Advanced English Grammar Lesson for ESL - Passive Voice

The first systematic grammars originated in Iron Age India, with Yaska (6th c. BC), Panini (4th c. BC) and his commentators Pingala (ca. 200 BC), Katyayana, and Patanjali (2nd c. BC). In the West, grammar emerged as a discipline in Hellenism from the 3rd c. BC forward with authors like Rhyanus and Aristarchus of Samothrace, the oldest extant work being the Art of Grammar (Τέχνη Γραμματική), attributed to Dionysius Thrax (ca. 100 BC). Latin grammar developed by following Greek models from the 1st century BC, due to the work of authors such as Orbilius Pupillus, Remmius Palaemon, Marcus Valerius Probus, Verrius Flaccus, and Aemilius Asper.
