William W. Goodwin's Greek Grammar is a comprehensive and accessible grammar of Classical Greek, first published in 1870 and a standard text in American schools. It helped shift the study of Greek from mere mechanical exercise to a genuine literary study, focusing on deep understanding, and is adapted for use in both schools and universities. In conjunction with other books, it combines several supporting readings, such as the first four books of Xenophon's Anabasis and selections from Xenophon, Plato, Herodotus, and Thucydides.
