1. Possessive Adjectives (MY / YOUR):
• They MUST be followed by a noun. They modify the noun to show who it belongs to.
• Examples: This is my bed. Keep your shoes here.
• ❌ Never say: “This is my.” (Incorrect because there is no noun).
2. Possessive Pronouns (MINE / YOURS):
• They stand ALONE and are NEVER followed by a noun. They are used to replace a [Possessive Adjective + Noun] phrase that has already been mentioned to avoid repetition.
• Examples: My bed is here, yours is there. (yours = your bed).
• ❌ Never say: “This is yours bed.” or “This is mine book.”
3. Quick Tip:
• If the blank is RIGHT BEFORE a noun ➡️ Choose My / Your.
• If the blank STANDS ALONE (at the end of a sentence, acting as an independent subject, etc.) ➡️ Choose Mine / Yours.
