LATIN Dictionaries

The dictionary is a powerful tool for learning Latin. After the grammar book, this is the most important resource for expanding your knowledge of the Latin language; once you reach intermediate-plus level in the Latinum Institute programme, it is time to start relying on Latino-Latinum resources as much as possible, to 'keep your head in Latin' and simulate to the degree possible in a world where there are no Romans, an immersive environment.

In the list of Latin books below you will find generalist dictionaries, and a second list of specialist subject-specific dictionaries for areas such as philosophy, zoology and chemistry.


GLOSSA - A Third Way Technologies. I like this unassuming Latin dictionary, it generates a drop-down list of words as you search, which is incredibly useful.

OLIVETTI MEDIA - Latin dictionary, and also has useful declension tables that are searchable. This dictionary gives very limited definitions, and few examples and sources. The glossa dictionary above is better.


Once a student reaches Intermediate-Plus level, they should be ready to move from a Latin-Vernacular dictionary to a Latin-Latin one. Unfortunately, there is currently no suitable student level Latin-Latin dictionary in print: we do have a number of dictionaries and thesauri that give Latin definitions that are useful for students, however, and I highly recommend spending time reading these, once your Latin is good enough. Dictionary reading is an excellent way to expand your knowledge of Latin.

Anon. Manulae Vocabulorum This dictionary gives very brief definitions of words in Latin - written for school pupils, this comes closest to what a student might require from a basic Latin-Latin schoolroom dictionary that I have seen so far.
