Are you ready for a real Farsi magic trick? In this lesson, we learn about a very special and mysterious rule involving the letter Vav (و). Sometimes, when you see the letters ‘kh’ (خ) and ‘v’ (و) and ‘aaa’ (ا) next to each other, the ‘v’ becomes silent and invisible to your ears! So even though you see ‘khwa’ (خوا) written down, you magically say ‘kha’ (خا). It’s a secret rule for just a few words like خواب (khâb – sleep).
