Forms

fidato (feminine fidata, masculine plural fidati, feminine plural fidate, superlative fidatissimo)[1]

Etymology

It is the past participle of fidare (“to trust”), used as an adjective.[1][2][3][4] The verb continues a Vulgar Latin *fīdāre (“to trust”), a remake of classical Latin fīdere (“to trust”).[5][1] The same verb is French fier, Occitan fizar, Catalan fiar, Spanish fiar and Portuguese fiar.[5]

The Latin verb and the noun fidēs (“trust, faith”), the source of fede, go back to Proto-Indo-European *bʰeydʰ- (“to trust”), which is also in Ancient Greek πείθομαι (peíthomai, “to obey, believe”) and in Gothic 𐌱𐌹𐌳𐌾𐌰𐌽 (bidjan, “to ask, pray”).[5][6]

Earliest recorded meaning

The TLIO's first record is the Roman Storie de Troia e de Roma of 1252–1258, in the sense “worthy of trust”.[7] DELI dates the adjective to Bartolomeo da San Concordio, before 1347, where wrongdoers bound by a shared secret become più fedeli e fidati, “more faithful and trusted”, to one another.[8][9] Nocentini and Devoto–Oli give a much later date, 1956, and Sabatini–Coletti the 14th century.[5][2][3]

Semantic evolution

Old Italian also used fidato for someone who trusts or feels safe, and for someone granted a safe-conduct: Boccaccio's Ghino di Tacco comes to court fidato, under a guarantee.[7][10] Boccaccio's lover goes to Pericone's house with alcuni suoi fidatissimi compagni, “some of his most trusted companions”.[9] Ariosto uses it for something familiar, one's fidato letto, and Manzoni as a noun, i suoi fidati, his trusted men.[11]

In modern Italian it is said of people one can trust, of places where one feels safe, and of products or machines of proven reliability.[12][2][3]
