Dravidian languages
The Semetic languages (sem) constitute a group of related languages and a branch of the Afro-Asiatic language family. Spoken by more than 470 million people throughout North Africa and Southwest Asia, the most widely spoken Semetic languages are Arabic, Maltese, Hebrew, Amharic, and Tigrigna.
The master plan involves generating independent finite-state transducers for each language, and then making individual dictionaries and transfer rules for every pair. The current status of these goals is listed below.
Status
The ultimate goal is to have multi-purposable transducers for a variety of Semetic languages. These can then be paired for X→Y translation with the addition of a CG for language X and transfer rules / dictionary for the pair X→Y. Below is listed development progress for each language's transducers and dictionary pairs.
Transducers
Once a transducer has ~80% coverage on a range of medium-large corpora we can say it is "working". Over 90% and it can be considered to be "production".

Dravidian languages by subgroup
The Dravidian languages form a close-knit family. Most scholars agree on four groups: North, Central (Kolami–Parji), South-Central (Telugu–Kui) and South Dravidian:
- Central (Kolami–Parji) languages
- Kolami-Naiki languages (Kolami)
- Parji-Gadaba languages (Duruwa, Gadaba)
- Northern languages (Brahui, Kurux, Sauria)
- Southern (Tamil–Tulu) languages
- South-Central (Telugu-Kui) languages
- Gondi-Kui languages (Gondi, Konda-Kui)
- Telugu languages (Telugu, Savara, Chenchu)
