Numbers 11-20( ارقام ٢٠-١١)

Double digits in Arabic look just like double digits in English: tens digit on the right and ones digit on the left. Also, just like 11-19 in English ١٩-١١ in Arabic also sound like some version of the ones digit and 10 together.

Ex: "Seven (7) " "Teen (10)" = sab3at (7) a3shara (10)

Also like English, you'll notice that ١١ and ١٢, (eleven and twelve) are a little different than the other numbers.
.احد drops the waaw at the beginning to become واحد
اثنان drops the nuun at the end to become اثنا


Notice the taa marbuuta's (demarcated in purple) in the Arabic names of the letters and the corresponding t's (demarcated in purple) in the transcriptions. Numbers ١٩-١٣ are in a grammatical structure that makes the taa marbuuta change in pronunciation from an "a" sound to a "t" sound. So for all numbers 13-19 remember to pronounce a "t" sound after the ones digit and before "a3shara".

The grammatical structure is called an iDaafa phrase and will be covered later.
Number 20/٢٠- The word for twenty in Arabic (شعرون /a3sharoon) does Number NOT resemble the word for two ( إثنان /ithnaan) like the word "twenty" looks like the word "two" in English. Why is this? Instead, the word for twenty in Arabic (عشرون/a3sharoon) looks related to the word ten in Arabic (عشرة / a3shara) because the word for twenty (عشرون/a3sharoon) literally means "two tens" in Arabic.
