Counting in Lojban

Language overview

Forty-two in Lojban Lojban (from logji and bangu, or logic language) is a syntactically unambiguous constructed language based on predicate logic, created in 1987 by The Logical Language Group. Lojban is derivated from Loglan, a language invented in 1955 by James Cooke Brown who claimed copyright on it, so Lojban started afresh from its lexical basis to create a whole new vocabulary.

Lojban numbering rules

  • Digits from zero to nine are specific words: no [0], pa [1], re [2], ci [3], vo [4], mu [5], xa [6], ze [7], bi [8], and so [9].
  • Compound numbers up to nine hundred and ninety-nine are formed by juxtaposing their composing digits names to each others. Thus, we can form pano [10] (one zero), vore [42] (four two), panono [100] (one zero zero), binoso [809] (eight zero nine)…
  • When three zeroes are following each other, the word for thousand (ki’o) is used instead of nonono (which is otherwise grammatically correct). Thousands are formed this way (e.g.: paki’o [1,000], ci paki’o [3,000], vo ki’o musore [4,592]).
  • Millions are formed the same way as thousands, i.e. by prefixing the million word (ki’oki’o) by its digit multiplier (e.g.: paki’oki’o [1 million], re paki’oki’o [2 million]). Higher scale numbers (billions, trillions…) are regularly formed the same way.
