ABSTRACT
The numbers in the range 13–19 have the suffix -teen. The numbers 13 and 15 have irregular forms of the base: thirteen, fifteen. The numbers from 20 to 90 have the suffix -ty. Intermediate numbers between 20 and 30 are made up of the number of tens and the appropriate basic number, e.g. twenty-five, thirty-nine, sixty-seven and so on. Three-digit numbers can also be read without the hundred and, so that 237 becomes two thirty-seven and 509 becomes five oh nine. Four-digit numbers are often split into two, so that 5,981 can be read as fifty-nine eighty-one. There are various types of distributive numbers in English. There is a number ump which never occurs in that form, but only in forms such as umpteen, umpty-ump(th). Ump is some unidentified relatively large number. There is a series of joke numbers for extremely large but imprecise numbers: zillion, gazillion, bajillion, and squillion.
