A number of historians and linguists including Peter Heather and Karl Heinrich Menges feel that the evidence only allows the Hunnic language to be positioned in the broad group of Altaic languages.
For this reason, many language families have had lumper–splitter controversies, including Altaic, Pama–Nyungan, Nilo-Saharan, and most of the larger families of the Americas.
Attempts have been made to relate it to many other language families, including Altaic, Austroasiatic, Austronesian, Nihali, and the putative Indo-Pacific stock.
On the occasion of his 75th birthday, Professors Karl Menges and Nelly Naumann prepared a Festschrift highlighting his career and including articles on Altaic languages.
