What is "ouxpo"

Ouxpo is an acronym for "Ouvroir d'X Potentielle". It is an umbrella group for Oulipo, Oubapo, Outrapo, etc. The term 'ouvroir', originally used in conjunction with works of charity, was reused by Raymond Queneau for a blend of 'ouvroir' and 'œuvre' ("work") and roughly corresponds to the English 'workshop'. The term 'potentiel' is used in the sense of that "which is possible, or realisable if one follows certain rules".
