Could it be because Rania ends in an alif/a and the Arabic word for woman begins with an alif so that the alifs are elided and therefore only one alif is pronounced? Update:I know the answer to your question now. The "-un" on the end of the words in the sentence that the indicate the words are in the nominative case, is only attached to words in sentences and not when the words are said by themselves. This is because a word by itself has no case. With the latest update, though, the MSA nunation seems to have been taken out of the sentences.
