Direct Action
Unlike English where we sometimes say 'intrude on', in Spanish, you usually just 'invadir' the thing directly. You don't need an extra small word like 'en' or 'sobre'.
The 'V' and 'B' sound
Mistake: “Pronouncing the 'v' like a sharp English 'v' with your teeth on your lip.”
Correction: In Spanish, 'v' and 'b' sound exactly the same. Keep your lips soft, almost like a light 'b' sound.
