Think Isn't Tink: Meet the Sound Between Your Teeth

Say 'think' and 'tink' back to back. If they sound the same to you, you're likely replacing English θ with a t sound, a common and very understandable habit since Portuguese has nothing like it. To make θ, your tongue tip needs to poke gently between your top and bottom teeth while air hisses through — no full stop like t, just a light friction. Try this: bite very lightly on your tongue tip, then blow air steadily for two seconds before releasing into a word. Practice 'think', 'thanks', and 'both', keeping that tongue position each time rather than pulling back to make a t or d. Spend two minutes just holding the position and hissing, no words yet — your mouth needs to learn the shape before it can move fast. This small shift makes a big difference in how easily people follow you.
