Pali
Pali‘ is commentaries (Atthakathas) of Buddhaghosa, which were written in 5th century A.D. The commentaries written by the Buddhaghosa, the term ‗Pali‘came to be regarded either as synonym for Buddha-vacana (words of the Buddha) or for the Tipitaka (original canonical texts). Buddhagosa mainly used the term Pali to distinguish commentaries from the original canonical text. (Tipitaka)
When Mahendra and Sanghamitra (son and daughter of King Asoka) went to Ceylon as Dhamma (Dharma)messengers, they carried with them the canonical language orally.
In order to distinguish the language of the text of the canon from Sinhalese bhasha‘, they used the term tanti‘ for the former.
