"The
Thesaurus linguae Latinae is the most authoritative dictionary of ancient Latin."
See an overview about what a word’s entry (entirely in Latin) generally offers. Be sure also to explore the
User Tools, so you know what you’re dealing with in a given entry. Finally, keep in mind that the TLL (in both print and digital form) is still a work in progress, offering entries for all words beginning with A-M and O-P, and for some words beginning with N and R.
