s’asseoir at C2 — literary & formal
On this page
Authority, arguments and the tax base.
The written register
Drop the pronoun and the verb turns abstract. « Asseoir son autorité » is to establish authority so that it rests on something solid — « le nouveau directeur a rapidement assis son autorité ». Scholarly writing uses the same image for arguments: « il a assis sa démonstration sur des archives inédites », grounded, not merely asserted.
The family goes further than most learners suspect. « L’assiette de l’impôt » is the tax base, the ground the tax sits on, nothing to do with dinner plates. « La cour d’assises » is the court that sits to try serious crimes. Both come straight from asseoir, and both live only in written, official French.
