Congratulations on reaching the end of Level 2 (Book 2)! Before you graduate to Verbs in Level 3, let's review the four most important concepts you've learned.
When bringing two nouns together to show possession ("The House of God"), the first word loses Al- and Tanween, and the second word is squeezed into Kasra (Majroor).
Detached pronouns are stand-alone words (I, He, They). Attached pronouns are suffixes glued to nouns to show possession (My, His, Their).
"In Arabic grammar, any group of non-human objects or animals is treated exactly the same as ONE SINGLE FEMALE (هِيَ)."
Nouns normally end in Damma. There are two main things that FORCE a noun down into the Majroor (Kasra) state.
