Voiceless TH vs T

path vs pat: hear and say the difference

path and pat are identical except for one sound: path has the voiceless th, /θ/, and pat has the t sound, /t/. T stops the air completely with the tongue on the ridge; TH never stops it — the tongue touches the teeth lightly and the air keeps hissing through.

Who merges this

Why this pair is hard

Hindi, Urdu, Punjabi, Bengali, Tamil, Thai and Vietnamese all map English TH onto a dental t, so the airflow stops where English wants friction. The fix is the same for all of them: move the tip forward to the teeth and refuse to close off the air.
