The Etymology of Cognoscenti
Cognoscenti is the Italian half of a pair English collected during the Grand Tour. Latin 'cognoscere' (to know thoroughly) gave Italian 'cognoscente' (one who knows) and French 'connoisseur' from the parallel verb 'connaître.' English borrowed the French form in the late 17th century and the Italian plural a century later, and the two now coexist in slightly different registers: 'connoisseur' for fine art, food, and wine; 'cognoscenti' for the cultured insiders of any niche. The deeper root is Proto-Indo-European '*ǵneh₃-' (to know), one of the most productive roots in the family — it gives Greek 'gnosis,' English 'know,' German 'kennen,' and Sanskrit 'jñāna,' as well as 'gnostic,' 'agnostic,' 'incognito,' 'recognise,' and 'noble.' The 'g' at the start of 'cognoscenti' marks the classical Latin form preserved through Italian; English 'know' has lost its initial sound but kept the silent 'k' as a fossil.
