What a surprise! I was always envious that Ørberg's famous book and approach had no counterpart for Ancient Greek. In fact in every bookstore I’ve checked books on learning Latin far outnumber those for Greek, if those exist at all. I learned Greek from Grouton’s From Alpha to Omega, a totally unappetizing book.

The reason, I think, for the difference is that, while there’s a robust tradition of using Latin in modern settings and a modernized vocabulary (see the many references given here: http://blogicarian.blogspot.com/2019/03/argumentum-ad-ignora...), the same is not true for Greek, which is a pity.

If you still have some resolutions to make for 2023 let this post be a sign to pick learning Greek! The book that’s most recommended to start with is Athenaze. Also, you can use the great and friendly community at Textkit (https://www.textkit.com/greek-latin-forum/) it also has texts of many good resource books. And there’s also the Perseus Digital Library with the goal of making all Greek material available: http://www.perseus.tufts.edu/hopper/
