Do you even finish a dictionary? Do you even read one? Or is it simply a reference?
This dictionary has helped me pass every single Latin exam I have ever taken, classical or medieval, from high school to my undergrad to my graduate language exam.
If you need a comprehensive resource for Latin, look nowhere else but here.
I used this constantly in college and grad school, and it never failed me! I also get it out occasionally now when I come across unfamiliar Latin terms in British parish registers.
