George Abraham Grierson, 1911 Encyclopædia Britannica (1911)
“ We have seen that the word “Prakrit” means “natural” or “vernacular,” as opposed to the “purified” literary Sanskrit. From this point of view every vernacular of India, from the earliest times, is a Prakrit. The Rig-Veda itself, composed long before the birth of “purified” Sanskrit, can only be considered as written in an old vernacular, and its language, together with the other contemporary Indo-Aryan dialects which never attained to the honour of “purification,” may be called the Primary Prakrits of India. ”
