السلام عليكم
We’ve looked at the three types of words that exist in Arabic. Now we’re going to look at how to tell which kind a word is. For each type there are certain signs that tell you immediately that a word is that type.
First, we’re going to look at the signs that tell us that a word is an اسم. There are some new words here, but don’t be alarmed because we’ll break it down for you.
فَالاسْمُ يُعْرَفُ: بَالْخَفْضِ وَالتَّنْوِيْنِ وَدَخُوْلِ الأَلِفِ وَالََلامِ وَحُرُوْفِ الْخَفْضِ
The ism is recognized by خَفْض, tanwin, the entrance of ا and ل, the particles of خَفْض.
