Middle Greek

In the middle, Greek does not entirely agree with Sanskrit in its personal endings, and the original forms cannot all be restored with certainty.

Mr. Putney not only made my membership in the class in "Middle" Greek possible, and practically free from embarrassment at being a late comer, but gave me many regular hours of private instruction in Homeric Greek, enabling me during the last weeks of the time to join the senior class in the study of the latter form of the language.

I should think your business would be to make yourself master of the middle Greek.
