Editing Language family (section)

===Complications===
Some exceptions to the simple genetic relationship model of languages include [[language isolate]]s and [[Mixed language|mixed]], [[pidgin]] and [[creole language]]s. 

Mixed languages, pidgins and creole languages constitute special genetic types of languages. They do not descend linearly or directly from a single language and have no single ancestor. 

[[Language isolate|Isolates]] are languages that cannot be proven to be genealogically related to any other modern language. As a corollary, every language isolate also forms its own language family — a genetic family which happens to consist of just one language. One often cited example is [[Basque language|Basque]], which forms a language family on its own; but there are many other examples outside Europe. On the global scale, the site [[Glottolog]] counts a total of 423 language families in the world, including 184 isolates.<ref>Cf.
