Original description: A complete genetic classification of the world's languages arranged in terms of 17 independent phyla. Languages are given in capitalized lower-case letters, groups in all capitals. Languages and groups preceded by + are extinct. The number of languages in each group is shown as [extant+extinct] after the name of the group. The tree is condensed, with ungrouped siblings listed together as branch ".0".
To make proper links for Wikipedia, the word "language" was added to all names apart from Western Desert Language.
All blue links have been confirmed to link or redirect to an article of the proper language family, though that does not guarantee the link is to the proper article.
