The Latin Lexicon (nicknamed Numen) is an online Latin dictionary (a dictionary of the Latin Language) and Latin grammar tool based on multiple sources, including both An Elementary Latin Dictionary (by Charlton T. Lewis) and A Latin Dictionary (by Lewis & Short). This online dictionary is different from any other you've ever used. It has been built from the ground up using AJAX technology to allow the fastest, most efficient and most useful user interface. Oh, and it includes macrons!
