@mennatallahmoham2: Using a or an before the singular noun a or an means one for example when I say a book I mean one book and when I say an orange I mean one orange we use an before the words that start with a vowel sound ( o-a-e-i-u) #minutes_for_english #grammar #englishgrammar #انجليزيـالمنهجــالجديد @Mennatallah Mohammed
