## Number 15 Meaning In English Words

To write and remember the correct spelling of 15 you better learn the language rules for writing numbers in words.

In English numbers from 1 to 12 are unique words that you have to remember. Numbers from 13 to 19 end with 'teen' and have the same begginning as is their last number. Starting from twenty all tens end with 'ty'. Tens where the second number is bigger than 0 are written by using a hyphen and simply writing the last number.

For numbers bigger than 100, a 'and' is placed before the tens (in American English the 'and' is optional). For the number 100 itself, 'a' or 'one' must be used. But 'a' can only be at the beginning of a number. The same principle of 'a' and 'one' applies to the hundreds(such as 1000, 402000 and so on).

Thousands are separated by commas. As a rule, the numbers are written in the singular. The plural is only used in dozen, hundred, thousand, million, billion if they are not specified by another number.
