As Soon As vs When: What’s the Difference and How to Use Them Properly

In addition, understanding proper placement aligns with grammatical rules about sentence structure, making your writing more polished and natural. Proper use also makes your speech sound more confident and fluent—an essential skill whether you're giving a presentation or just chatting.
