Elamo-Dravidian languages
The Elamo-Dravidian language family is a hypothesised language family that links the Elamite language of ancient Elam to the Dravidian languages of South Asia. Later versions (2015—) of the hypothesis entail a reclassification of Brahui as being more closely related to Elamite than to the remaining Dravidian languages. Linguist David McAlpin has been a chief proponent of the Elamo-Dravidian hypothesis, followed by Franklin Southworth as the other major supporter. The hypothesis has gained attention in academic circles, but has been subject to serious criticism by linguists, and remains only one of several possible scenarios for the origins of the Dravidian languages. Elamite is generally accepted by scholars to be a language isolate, unrelated to any other known language.
