Latin Dictionary and Grammar Aid

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.

Stem: Ending:

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.

For a program with a better understanding of Latin grammar and a larger vocabulary (39,000 words), try

William Whitaker's Words.

PLEASE download Words and install it on your computer.

If you have Windows, Macintosh, or DOS, you can use it offline.

William Whitaker's Macintosh version should work with OS X up to 10.7, though it might be necessary to install Rosetta, which used to come with OS X but was not always installed by default. For OS X versions 10.7 and later, try Erik Mendoza's Interpres.

In Windows, The Words program operates from the old DOS-like command line. You can make it better by right-clicking the top left corner and changing the font, size, and colors. Alexei Grishin offers a free Windows interface for it. A commercial product called Blitz Latin, produced by Dr. John White in collaboration with William Whitaker, can translate texts from Latin to English automatically.

William Whitaker's Words program also provides the translation mechanism for VulSearch, an excellent free Windows program for reading and searching the Vulgate and Glossa Ordinaria.

Marco Waclawek has developed a Latin - German Dictionary based on William Whitaker's Words.

See also the Latin dictionary at the Perseus Project, an online version of the Lewis and Short Latin Dictionary.

Latin Wordlist and Grammar Aid

Lynn Nelson produced this wordlist to help students read Medieval Latin. He warns that it is not an exhaustive list, and it is only a list, not a dictionary. The gender and declension of nouns is not provided nor is the conjugation of verbs. It contains fewer than 6000 words. Type in a Latin phrase or word. Press the button (or Enter). Cross your fingers.


This grammar reference list, also produced by Lynn Nelson, presently contains two sections: examples of translations for the various uses of several noun cases, and the endings for regular nouns, adjectives, active verbs, and present participles.

Search using the form "*ending". n=noun, a=adjective, v=verb, p=present participle. If you find that the ending is that of a form of the noun or adjective that is unfamiliar to you, turn to the first section for the different uses of the cases.
