• ❌ Never use: “We will take your.” (It needs the noun “car”!).

• Rule: These pronouns STAND ALONE and are never followed by a noun. They replace a [Possessive Adjective + Noun] phrase that has already been mentioned.
• Context: When comparing the two cars to avoid repeating the word “car” over and over. “My car is old, so let’s take yours.” (yours = your car).
• ❌ Never use: “Let’s take yours car.”

• Look at the word immediately after the blank.
