W. Schmidt has established, as is well known, a new family of human speech, termed by him the “ Austric ” family. It was constituted by joining an “ Austronesian ” and an “ Austroasiatic ” group of languages; the latter term was coined by Schmidt when he found that the Mon-Khmer and some other languages of the East are kindred to the Muṇḍa languages of India. Schmidt's treatise on the matter was declared by some scholars to be “ masterly ”, whereas others, so Przyluski, advised reserve. As a matter of fact, the existence of an “ Austric” family of languages—the most widely diffused on earth—is actually uncontested. That the morphology and the grammar of the Muṇḍa and the Mon-Khmer languages are quite different, is admitted by W. Schmidt himself. Thus he based the relationship upon some similarities in phonetics, on the use of infixes in both languages, and on the results he obtained by comparing words.
