LESSON 3 · Everyday Expressions & Idioms
Build Your Slang Vocabulary
Adopt slang naturally with these steps:
- Start with the safe tier — get comfortable with the everyday basics before reaching for anything edgier
- Mirror the people around you — if your coworkers say "sounds good," adopt it; if they say "brilliant," match them
- Test one new word per week in low-stakes situations like texting or casual chat
- Never use slang you cannot define — if someone asks what it means and you cannot explain, you are not ready
- Avoid slang in formal writing — emails to your boss, cover letters, and presentations are slang-free zones
The goal is not to sound like a teenager.
