Extra Tips for Mastery

Pronunciation alert!
Words like tough, though, through, and thought all have wildly different pronunciations — even though they look alike. Don’t let spelling trick you. Listening is key here. Pay close attention when watching shows or talking with native speakers. - Use memory tricks:
- Tough = like “rough” (rhymes).
- Though = sounds like “go.”
- Through = rhymes with “blue.”
- Thorough = rhymes with “burrow.”
- Practice in context.
You can memorize definitions all day long, but what really helps is seeing the words used in meaningful situations. That’s why apps like Lexiphant focus on letting you capture words from your real-life experiences — like movies, articles, and conversations — and review them in your own context.
