Today’s word: milliard (Fr) and milliárd (Hu).
In English, it means “billion.”
“Billion” belongs to two different number-naming systems, the long scale and the short scale. Be careful when you see “billion” in a non-English text—this word can mean two very different numbers! In the short-scale system (with which Americans are most familiar), “billion” equals 1,000,000,000. The prefix bi- here refers to the multiplication of one thousand by one thousand squared (1,000 x 1,000^2). In the long-scale system (used by the French and Hungarians), the prefix bi- refers to the exponent of one million (1,000,000^2), producing the number 1,000,000,000,000.
