TH ஐ எப்படி உச்சரிப்பது: நீங்கள் "think" என்று பொருள்படும் போது "sink" என்று சொல்லுவதை நிறுத்துங்கள்

Most languages simply do not have the TH ஒலிகள், so the brain swaps in the closest sound it already knows. Think comes out as “sink”, “fink” or “tink”; this becomes “zis”, “dis” or “vis”. Native speakers usually still understand you, but they notice it every single time.

The good news: TH is one of the easiest sounds to fix, because you can see and feel what you are doing.

இரண்டு ஒலிகள், ஒரு நாக்கின் நிலை

English has two TH sounds. They use exactly the same mouth position; the only difference is your voice.

ஒலி	உதாரணங்கள்	குரல்
/θ/	think, three, bath, month	ஒலியற்ற — காற்று மட்டும்
/ð/	this, the, mother, breathe	ஒலியுள்ள — உங்கள் தொண்டை புழங்குகிறது

Put a hand on your throat. Say a long “ssss”, then a long “zzzz”. The second one buzzes. That buzz is the whole difference between /θ/ and /ð/.

நாக்கு எங்கு செல்கிறது

1. Relax your jaw and open your mouth slightly.
2. Put the நாக்கின் முனை பற்களின் இடையில் மெதுவாக வைக்கவும் — just the tip, not the whole tongue.
3. Blow air gently over it. Do not press, and do not bite.

Hold a finger in front of your lips. If the tip of your tongue can almost touch it, you are doing it right.

The most common mistake is moving the tongue back to make the sound “cleaner”. The moment the tongue hides behind the teeth, you get /s/, /t/ or /f/ again.

30-வினாடி பயிற்சி

Say each pair slowly, then fast. Feel the tongue move forward on the second word.

1. sink — think
2. sank — thank
3. tree — three
4. zen — then
5. day — they

Then read this sentence three times, a little faster each time:

I think this thing is worth three thousand.

ஏன் ஒரு ஆசிரியர் இதை கவனிக்காமல் போகலாம் — ஆனால் ஒரு ஆப் கவனிக்காது

When you speak a whole sentence, a listener’s brain fills the gaps, so a missing TH is easy to overlook. HolosAccent scores ஒவ்வொரு ஒலியையும் தனித்தனியாக, so a think that came out as “sink” is flagged on the exact sound — /θ/ → /s/ — instead of just lowering an overall score.

Two minutes a day on TH words is usually enough to make the new tongue position automatic within a couple of weeks.
