académiser

A rare, mostly critical neologism meaning to make something academic — to institutionalize or formalize an art form or practice, often implying it loses spontaneity in the process (académiser le street art).

• Certains critiques reprochent aux musées d'académiser le street art. — Some critics accuse museums of turning street art into an academic exercise.
• Le risque est d'académiser une pratique née dans la rue. — The risk is institutionalizing a practice born in the street.
• Ce cursus a fini par académiser une discipline autrefois informelle. — This program ended up formalizing a once-informal discipline.

A very rare word confined to art/cultural criticism — a learner is unlikely to ever need to produce it, only perhaps to recognize it in a review or essay.
