Overview
English number words include numerals and various words derived from them, as well as a large number of words borrowed from other languages.

Fractions and decimals
Numbers used to denote the denominator of a fraction are known linguistically as "partitivenumerals." In spoken English, ordinal numerals and partitive numerals are identical with a few exceptions. Thus "fifth" can mean the element between fourth and sixth, or the fraction created by dividing the unit into five pieces. When used as a partitive numeral, these forms can be pluralized: one seventh, two sevenths. The sole exceptions to this rule are division by one, two, and someti…
Whether or not digits or words are used
With few exceptions, most grammatical texts rule that the numbers zero to nine inclusive should be "written out" – instead of "1" and "2", one would write "one" and "two".
Example: "I have two apples." (Preferred) Example: "I have 2 apples."
After "nine", one can head straight back into the 10, 11, 12, etc., although some write out the numbers until "twelve".
