Catalan

Noun

trilió f ‎(plural trilions)

1. (cardinal) trillion (long scale), quintillion (short scale); 10¹⁸; 1,000,000,000,000,000,000

Usage notes

• Milió, bilió and larger numbers are followed by de or d' unless a smaller number comes between milió, bilió, etc and the item being counted. Hence:
  • El gratacel va costar mil tres-cents quaranta-dos milions d'euros.

    The skyscraper cost one thousand three hundred forty-two million euros.

  • Un milió sis-centes quinze mil nou-centes vuit persones resideixen a Barcelona.

    One million six hundred fifteen thousand nine hundred and eight people reside in Barcelona.

• Unlike cent or mil, milió, bilió and larger numbers are often preceded un or una when there is only one of them.
• Catalan uses the long scale except when intentionally forming calques of short scale terms from other languages.
