In the counting system used in the Cornish language the numbers below 100 are based on twenties, as in the French numerals for 60-99, where numbers from 21–39 are "x on twenty", 41–59 are "x on two twenty", numbers from 61–79 are "x on three twenty", and numbers from 81–99 are "x on four twenty". 40 is "two twenty", 60 is "three twenty", and 80 is "four twenty"
