Forms

diamant m (plural diamants)[1]

Etymology

It is inherited from Late Latin diamas (“diamond”), a form recorded on curse tablets, probably a metathesis of *adimas (the source of aimant) under the influence of Greek words beginning with διά (diá).[2][3][4] The classical Latin form is adamās (“steel, diamond”), from Ancient Greek ἀδάμας (adámas), first “iron, steel”, then “diamond”.[5][6] Littré explains the Greek word as “that cannot be tamed”, from the privative ἀ- (a-) and δαμάω (damáō, “to tame”).[7]

Cognate with Italian diamante, Spanish diamante, Portuguese diamante, Occitan diaman, Catalan diamant and Romanian diamant.[8][7][9] The English word diamond was borrowed from French in the 14th century.[8]

Earliest recorded meaning

It is first found in Floire et Blancheflor (late 12th century), in a list of precious stones: Diamanz et amacites.[2][6]

Semantic evolution

The word has always named the precious stone.[4] From 1549 pointe de diamant was a glazier's tool tipped with a diamond, which diamant alone named by 1676.[2][4] Figurative uses draw on the stone's brilliance (late 15th century), its hardness (1625, Racan), its purity and its price;[6] hence croqueuse de diamants, a woman who spends lavishly.[4]

In New Caledonia and in ornithology diamant de Nouméa names a bright green bird with a red head and breast.[4]
