Three Isn't 'Tree': The Sound English Squeezes Between Your Teeth

English has a sound produced by placing your tongue tip between your teeth and pushing air through, found in words like 'three' and 'this,' but Ukrainian has no direct match, so speakers frequently substitute 't,' 'd,' or 's' - turning 'three' into 'tree' and 'this' into 'dis.' This substitution pattern is one of the most consistently identified features of Ukrainian-accented English. Getting it right just means changing where your tongue goes: instead of touching the roof of your mouth for 't,' let your tongue tip poke gently between your top and bottom teeth and keep air flowing steadily. Try 'three/tree,' 'thin/tin,' 'this/dis(h).' Today, say each pair slowly in front of a mirror, checking that your tongue actually shows between your teeth for the 'th' word. Two minutes of this contrast practice trains both your ear and your muscles. This one adjustment clears up a lot of confusion - you've got this!
