"Formal French" is planned, but the language goes on without it.

For example, the AF is oblivious to https://en.wikipedia.org/wiki/Verlan (unless a word there ends hitting common usage)

> Some verlan words, such as meuf, have become so commonplace that they have been included in the Petit Larousse[3] and a doubly "verlanised" version was deemed necessary, so the singly verlanised meuf became feumeu; similarly, the verlan word beur, derived from arabe, has become accepted into popular culture such that it has been re-verlanised to yield rebeu
