Forms

interessante m or f by sense (plural interessanti, superlative interessantissimo)[1]

Etymology

It is from Italian interessare + -ante, the present participle used as an adjective.[2][3][4][5][6] DELI and Treccani note the influence of French intéressant (1718), which is why the purist Antonio Cesari opposed the word.[2][7]

Interessare is a denominal verb from interesse, a learned word from Medieval Latin interesse, the Latin infinitive of intersum (“to be between; to matter”) used as a noun in the Middle Ages.[2][3] Nocentini describes it as a legal term meaning “advantage, profit”, from the impersonal use “it matters”, literally “it is in between”.[3] The Latin verb is formed from inter- (“between”) and sum (“to be”).[2] Panzini wrote that the noun, the verb and the adjective had been taken from French long ago but were so common that condemning them was pointless.[2]

Earliest recorded meaning

The first record is in Francesco Algarotti's Lettere filologiche (1756), and the word is also in Antonio Cocchi before 1758, in the sense “arousing interest”.[2][6] Cocchi writes of osservazioni naturali e interessanti “natural and interesting observations”.[8]

Semantic evolution

In the 18th and 19th centuries the word kept a foreign flavour: Tommaseo–Bellini quotes Fanfani's judgment that it is “not a nice word” when used as an adjective.[9] It became common all the same, for what is worth attention, for an advantageous price or offer, and for a person who attracts others by qualities of mind.[10][11][4] The euphemism in stato interessante means “pregnant”, and fare l'interessante means to put on airs in order to attract attention.[4][6][7]
