There are far too many websites about Classics and Latin for me to even count, let alone list. I touch on just a few here.
Texas Classical Association includes many useful links
Some reasons to study Latin can be found here
The “Joyful Latin Learning” web site is valuable for all students of Latin
The American Classical League is an organization for all Classicists
William Whitaker’s amazing Latin dictionary, which I highly recommend, can be downloaded for free.
Marcus Tullius Cicero, a brilliant Roman writer and orator, has his own web page
You can find many Latin phrases at this British web site.
There is also a Latin chat group here which you can join.
This site will explain the roots, origins and derivations of many words.
And believe it or not, you can read or listen to the news of the world in Latin here at Nuntii Latini.
Excellent video by Terry Jones (formerly of Monty Python) about the realities of life in ancient Rome is available here.
Oerberg’s Lingua Latina is a very highly regarded Latin text, very accessible.
