📝 Essential Grammar Rules
✅ Comma Usage
Use commas before AND, BUT, OR, and SO when connecting two complete sentences. No comma needed for simple lists or phrases.
🔗 Sentence Structure
Pattern: [Idea 1] + [connector] + [Idea 2]. Make sure both parts make sense together.
🎯 Choose the Right Connector
AND = addition, BUT = contrast, OR = choice, SO = result. Think about the relationship between your ideas.
⚠️ Common Mistakes
Don't overuse "and" in one sentence. Don't combine "but" with "however". Always check your comma placement!
