Wa Alaikom Asalam dear student Ahmed.Well, when I say C it means Consonants. and when I say V it means Vowel. and of course you know that " a, e, i, o, u," are the vowels and the other 21 letters are the consonants.for example. Set is CVCbecause s=C , e=V and t= C so it will be CVCanother example.hurt is CVCC can you tell me why?
