Did you know that in Arabic words always begin with a consonant and end with a vowel? In this way it's very different from most English words that feature two consonants and sometimes silent letters. This free online course teaches you how to use the fourth and twenty-fifth letters of the Arabic alphabet.We begin with 'Thaa2 (ث)' the fourth letter which sounds like the English 'Th'. We examine 'Thaa2 (ث)’ with short and long vowels and explain its use with Tanween Fat7ah Damah and Kasrah. The course shows you how to write the letter depending on its position in a word.We then move on to the twenty-fifth letter in Arabic: ‘Noon (ن)’. Once again we analyze it with short and long vowels as well as with Tanween. Arabic letters can have four different forms depending on their position in a word. We explain how the letter links to those before or after it. This course suits anyone who wants to explore the beauties of Arabic by learning the letters ‘Thaa2 (ث)’ and ‘Noon (ن)’.
