billionaire
UK: ˌbɪljəˈneə(r) | US: ˌbɪljəˈner
n. a person whose wealth amounts to at least a billion (units of currency, e.g., dollars, pounds).
The word "billionaire" combines "billion," a numerical term adopted from French in the 17th century (originally from Italian "billione," meaning "a million squared"), with the suffix "-aire," derived from French "-aire" (Latin "-arius"), indicating a person connected to something. The term emerged in the mid-19th century as industrial wealth expanded, reflecting societal fascination with extreme wealth. The suffix "-aire" is also seen in words like "millionaire" (coined earlier, in 1821) and "doctrinaire."
