Here's a short story:

Pali is a Prakrit language native to the Indian subcontinent. It is widely studied because it is the language of much of the earliest extant literature of Buddhism as collected in the "Pāli Canon" or "Tipiṭaka" and is the sacred language of some religious texts of Hinduism and all texts of "Theravāda" Buddhism. 

The word Pali is used as a name for the language of the Theravada canon. According to the Pali Text Society's Dictionary, the word seems to have its origins in commentarial traditions, wherein the "Pāli" (in the sense of the line of original text quoted) was distinguished from the commentary or vernacular translation that followed it in the manuscript. As such, the name of the language has caused some debate among scholars of all ages; the spelling of the name also varies, being found with both long "ā" and short "a" , and also with either a retroflex or non-retroflex "l" sound. Both the long ā and retroflex ḷ are seen in the ISO 15919/ALA-LC rendering, Pāḷi; however, to this day there is no single, standard spelling of the term, and all four possible spellings can be found in textbooks. R. C. Childers translates the word as "series" and states that the language "bears the epithet in consequence of the perfection of its grammatical structure". (End of story)
