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.
