Glottopolitics is a sociolinguistic concept coined by Jean-Baptiste Marcellesi and Louis Guespin.
It may be defined as any action taken by society to manage language interaction.
Glottopolitics is constantly at work; it is a continuum that ranges from minuscule acts to considerable interventions, ultimately concerning language itself: promotion, prohibition, change of status, etc.
There can be no social community without glottopolitics.
[1] It is a social practice from which no one can escape (people "do glottopolitics without knowing it", whether they are ordinary citizens or ministers of the economy).
