connoisseur (English)

Where does "connoisseur" come from?

The English word 'connoisseur' entered the language between 1705 and 1715 as a borrowing from the French 'connoisseur'[1]. This French term is a derivative of the verb 'connaître', which means 'to know'[1]. The lineage of this verb traces back to the Old French 'conoistre', which itself descended from the Latin 'cognōscere' and the Late Latin 'conōscere'[2]. Ultimately, the word is anchored in the Proto-Indo-European root '*ǵneh₃-', which relates to the concept of knowing[1]. The development of the French form is notable as one of the few instances where the spelling 'oi' shifted in pronunciation to a sound similar to 'ai' rather than the typical 'wa' sound[2].
