miliarda

Miliarda is a numeral name used in several languages to denote the number 1,000,000,000 (one thousand million). It appears in various spellings such as miliarda, miliard, or milliard, with the exact form depending on the language and its grammar.

Etymology and forms: The term is built from a root related to milli- (thousand) and a suffix used in numeral formations. Related forms appear in nearby languages and in English as milliard. The feminine form miliarda arises in languages with gendered nouns or inflection.

Regional usage: In languages such as Romanian, Polish, Russian, Bulgarian, and Ukrainian, a form of miliard signifies 10^9. Spelling and gender can vary by language (for example, miliarda or miliard), but the intended value remains the same in those contexts. In English and many other Western languages, the short-scale name for 10^9 is billion, though some languages retain a form equivalent to milliard for historical or conventional reasons.

Scale and naming: The distinction between short scale and long scale affects what is called a billion or a milliard. In the short scale (used in most English-speaking contexts), 10^9 is typically called a billion. In the long scale (historically used in parts of Europe), 10^9 was often called a milliard, with 10^12 named billion. Some languages continue to use miliarda or its variants for 10^9 regardless of the broader scale system.
