Latin Dictionary and Grammar Aid
From the page:
"Type in the form of the word that you would expect to find in a dictionary or a truncated form of the word (e.g., stem only). If you want help with the ending of a word, type the ending in the space provided. (If you prefer, you may leave this space blank). To see all the words in the dictionary that begin with "q", search for "q" as the stem. You can also translate English to Latin."
"This dictionary defines about 15,600 words. Florin Neumann, who found the data on the Internet and reformatted it for the Macintosh, says that it may not be used for commercial purposes. Matt Neuburg reformatted it so that it would operate on the Macintosh as a memory-resident searchable dictionary. I reformatted the dictionary again and wrote scripts to search it together with Lynn Nelson's grammar aid to produce the answers you find here."
