This article is missing information about the linguists who agree, disagree, and doubt the proposed language families. Please expand the article to include this information. Further details may exist on the talk page.(August 2023)
The following is a list of proposed language families, which connect established families into larger genetic groups (macro-families). Support for these proposals vary from case to case. For example, the Dené–Yeniseian languages are a recent proposal which has been generally well received, whereas reconstructions of the Proto-World language are often viewed as fringe science. Proposals which are themselves based on other proposals have the likelihood of their parts noted in parentheses.
