Recently I have had e-mail from readers asking for advice about studying Latin this summer.
My best advice is, no matter what books you use, work out loud and everyday.
Working out load, reading and listening, gets those pathways open.
Everyday.. well… repetita iuvant.
Here are some books you might need.
I like the Latin Dictionary Founded on Andrew’s Edition of Freund’s Latin Dictionary otherwise known as "Lewis and Short" published by Oxford Univ. Press.
You can get by at entry level with Cassell‘s
If you are more advanced, you might want the Dictionnaire etymologique de la langue latine
And Souter, which supplements the L&S.
And if you are liturgically inclined the Le vocabulaire latin des principaux thèmes liturgiques by Albert Blaise reworked by Antoine Dumas.
