List of proposed language families

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.

Widely rejected
Below are language families that are already rejected by most linguists. Since it's widely rejected, only linguists who agreed will be shown.
