The question is ' arabic is not like western languages,say spanish,which has not difficulty if you have learned all the consonants and vowels cause you can spell and speak all the letter combation correctly by yourself. But i find arabic language is a bit different, although you have learned all the consonants and vowels you still can not spell and pronounce the letter combinaton correctly as the radio teaches you. For example, the arabic symbol vowel ( َ ) changes a bit when is spelled together with the consonants like خ ر ص ض ط ظ ق ع و ی，in these letter combinations, the symbol vowel ( َ )sounds like 'u' in the word 'but',but if combined with the other consonants, the symbol vowel( َ ) sounds close to 'e' in the word 'bed'. So i can't use the common rule to read them but remember and mimic them one by one !T
