Arabic Ordinal Numbers
Ordinal Arabic numbers in Arabic are almost like the cardinal numbers, with some exceptions in the numbers from 1 to 10, and a slight difference in numbers from 11 and up.
Note that ordinal Arabic numbers are somehow like adjectives, so they have to take the masculine, or feminine form.


So in ordinal Arabic numbers After 10 only the first number takes the feminine, for example 13th in Arabic numbers is thaleth achar for masculine, and thalethata achar for feminine, achar stays the same, the first half “thaleth” which means 3rd takes “a” in the feminine, and so does the rest of the ordinal Arabic number, except ten numbers like 20, 30, 40, 50, they look like cardinal numbers but they add “a” as a prefix for numbers starting with a consonant, for example: 70 = sab’un, 70th = asab’un (for both masculine and feminine), and they add “al” for ten numbers starting with a vowel, like: 40= arba’un, 40th = alarba’un.
