No idea if anyone learns Latin these days (possibly I am the only sad case out here...) but if anyone does use and/or is learning Latin, this website is brilliant. It's not just a Latin dictionary (though it links to the classic Latin dictionary (Lewis and Short); the beauty of it is that even if you don't have the dictionary form of a word (e.g. if you only have the 2nd person plural imperfect subjunctive of a verb, or the ablative plural of a noun) it will analyse it for you and tell you which dictionary form you need to look up and what grammatical form it might be. It is really fab (... if you're into this sort of thing )
Budding classicists, enjoy...
