Geography & History The Buddhist Canon in Sri Lanka is written in Pali, so the language is still used as a sacred one in Sri Lanka, Myanmar, Thailand, Laos, Cambodia and Vietnam. But its homeland is India, and Pali originally was one of western dialects which later acquired certain eastern characteristics. Later together with Buddhism it spread within the South Eastern Asia, and a lot of scientific, religious and literature works were written in it already when it was forgotten in India. There are in fact four kinds of Pali: the Canon Pali, the literature Pali, the commentary Pali and the modern Pali; the last one has got a significant number of local borrowings and peculiarities and is no longer classical.
Phonetics Pali phonetics is rather simple: 5 simple vowels, no diphthongs and sonant vowels, aspirated and non-aspirated consonants. Pali phonetic laws prohibit the usage of a great number of fricative consonants together, all words end in a vowel. 
Nominal Morphology In morphology the number of vowel interchanges decreased in comparison with Sanskrit; there is a trend of unification of types of noun declension and verb conjugation, and the number of cases is six at maximum. 
Verbal Morphology The verb has only three tenses and two aspects: ancient Indic languages Vedic and Sanskrit used much more of them. The system of syntax is well developed and uses many auxiliary parts of speech in analytical constructions. 
Lexicon Pali is interesting for its vocabulary which is totally unnatural and is created only in order to reflect the ideas of the religion. 
Writing Brahmi script
Close Contacts Languages of the Southeast Asia contributed much to the "modern" variety of Pali. Of the Indic languages, Pali is rather similar to Sanskrit.
