Pronunciation

• (Portugal) IPA^(key): /tɾiˈʎɐ̃w̃/

• Hyphenation: tri‧lhão

Noun

trilhão m (plural trilhões)

1. (Brazil, cardinal number) trillion (10¹²)

   Synonym: (Angola, Portugal) bilião

2. (Portugal, informal, cardinal number) Synonym of trilião (“10¹⁸”)

Usage notes

• Portuguese-speaking countries follow the traditional long scale, with the exception of Brazil which adopted the short scale used in the UK and US. The number 10¹² is expressed as um bilião in African and European Portuguese, but as um trilhão in Brazilian Portuguese.
• The Angolan Government proscribes the use of long scale.
• In Portugal, the alternative um trilhão (“one quadrillion, 10¹⁸”) is an informal spelling of the preferred and proscribed um trilião.
