Forms

millionnaire m or f by sense (plural millionnaires)[1]

Etymology

It is formed from French million + -aire.[2][3][4][1] Littré reports the tradition that it was coined in the vogue of John Law's financial system.[5]

Earliest recorded meaning

The Grand Robert, the Petit Robert and the DHLF date the word to 1721, of a person who owns a million or more;[4][6][3] the TLFi's first quotation is from Lesage's La Valise trouvée (1740).[2]

Semantic evolution

The word first described someone whose fortune ran to millions, and by extension anyone very rich, a sense the GLLF dates from Balzac (1846).[2][3][7] Phrases such as millionnaire en dollars specify the currency.[3][2] The compound multimillionnaire followed in 1898,[3] and in modern French a ville millionnaire is a city of at least a million inhabitants.[6] English took millionaire from French in 1821.[8]
