/θ/ vs /t/: three vs tree
In short
The soft dental /θ/ and the crisp /t/ separate three/tree, thin/tin and thought/taught. A low-load but highly visible contrast: 'tree people' instead of 'three people' is instantly heard. This contrast carries a LOW functional load, it separates few word pairs, so while the substitution is noticeable, it rarely blocks understanding. Treat it as polish, not priority.
How to hear (and make) the difference
/θ/ is a continuous airflow with the tongue between the teeth; /t/ is a complete stop behind the teeth. If the sound stops and pops, it was a /t/.
Most challenging for Hindi, Urdu, Bengali, Russian, Vietnamese, Tagalog speakers.
