pouvoir (French)

Where does "pouvoir" come from?

The French noun 'pouvoir' traces back to an infinitive verb inherited from Middle French 'povoir', which came from Old French forms including 'povoir', 'pooir', and earlier 'podeir'[1][4]. These Old French forms derived from Vulgar Latin 'potēre', an analogical regularization of classical Latin 'posse'[1][3], with 'potēre' itself attested by the sixth century CE[3]. The Latin verb originated as a compound from Proto-Italic '*possom', combining '*potis' meaning 'master in control of' and '*som' meaning 'to be'[2]. As the word developed in French, the intervocalic dental consonant was lost, and a 'v' sound was eventually inserted to break the resulting vowel hiatus[1].
