Cardinal Numbers from 1 to 10
Some examples of the uses of 1 and 2
You may recall from Book Two (p.45) that the number 1 can be conveyed through the use of tanween, and the number 2 through the use of the dual. However, there are times when it will be necessary to use the numbers 1 and 2 in a sentence. Note that, unlike the numbers from 3 to 10, the numbers 1 and 2 follow the gender of the nouns they describe and come after the noun, not before it. The examples below illustrate various ways of expressing 1 and 2.

You may recall from Book Two (p.45) that the plural in Arabic starts from number three rather than two. You may also remember that the key rule governing the usage of numbers from 3 to 10 is that the feminine form of numbers is used when referring to masculine nouns, and the masculine form of numbers is used when referring to feminine nouns. The noun is usually written after the number describing it, and is used in the plural form. It takes a genitive ending (i.e. a kasra or two kasras). As for the number itself, it is fully declinable and can therefore take a damma, fatha or kasra depending upon its role (and hence case) within the sentence.
