The "th" sound is the one that trips up almost everyone. You say "think" and it comes out like
"tink". You say "this" and it sounds like "dis". You are not wrong as a person, the sound just does
not exist in many Indian languages, so your tongue never learned it. That is normal. The good news
is that "th" is one simple tongue position, and once you find it, dozens of words click into place.
You do not need a perfect accent. You need a clear tongue. Let us find the sound together, slowly
and kindly.
Quick answer: The "th" sound is made by putting your tongue tip gently between your teeth and
pushing air out. There are two versions: a soft one in "think" and "three", and a buzzy one in
"this" and "mother". The fix is simple: tongue between teeth, not behind them. Practise minimal
pairs like "think/tink" and "this/dis" until the new sound feels natural.
Why is "th" so hard for Indian speakers?
It is hard because most Indian languages do not use it. Your tongue is trained to make "t", "d",
"th" (as in "Thomas"), but not the soft "th" where the tongue touches the teeth. So your mouth
swaps it for the nearest sound it knows.
That swap is why "think" becomes "tink" or "think" with a hard "t". Your tongue is doing the right
thing for your first language. It just needs a new position for English.
"I said 'tank you' for years and never knew. The day someone showed me to put my tongue between
my teeth, the sound came out on the first try. I felt so relieved it was that simple."
So this is not a talent problem. It is a tongue-position habit. New habit, new sound. You can do
this.
How do I actually make the "th" sound?
Here is the whole secret: put the tip of your tongue lightly between your top and bottom teeth,
then push air out. That is it. There are two types.
Soft "th" (no voice, just air) — think, three, bath:
- Tongue tip between teeth.
- Blow gentle air. You should feel air on your tongue.
- No buzz in your throat. It is a quiet, airy sound.
Buzzy "th" (with voice) — this, that, mother:
- Same tongue position, between the teeth.
- Now add a buzz in your throat. Feel it vibrate.
- The air carries a soft hum.
Try it: hold your finger near your mouth and say "three". You should feel a small puff of air on
your finger. If you feel no air, your tongue is too far back.
Do not press hard. Light tongue, gentle air. If you push too hard, it sounds forced. Soft is
correct.
Say this, not that: common "th" mistakes
These are the usual swaps. Read each correct word a few times with your tongue between your teeth.
- ❌ "tink" (hard t) → ✅ think (tongue between teeth, soft air)
- ❌ "dis" (hard d) → ✅ this (tongue between teeth, with buzz)
- ❌ "tree" for "three" → ✅ three (air, not a hard t)
- ❌ "wid" for "with" → ✅ with (end on the th sound)
- ❌ "mudder" for "mother" → ✅ mother (buzzy th in the middle)
- ❌ "tirty" for "thirty" → ✅ thirty (soft th at the start)
Useful minimal pairs to train your ear and tongue:
"think" vs "sink" vs "tink" — only the first is right.
"three" vs "tree" — say both. Feel the air in "three".
"they" vs "day" — "they" buzzes between the teeth; "day" hits behind the teeth.
Say each pair slowly. When you can hear the difference, you are halfway there.
What about "th" at the end of words?
End "th" sounds get dropped a lot, and that loses meaning. Keep your tongue between your teeth
right to the end of the word.
- soft end "th": bath, math, both, mouth, fourth, health
- buzzy end "th": breathe, smooth, with, clothe
"I take a bath" — finish the "th". "I take a baf" or "bat" changes the word.
Numbers are a great place to practise end "th": fifth, sixth, seventh, twelfth. They come up in
dates and prices all the time, so a clear ending really helps people understand you.
How do I tailor "th" practice to my own words?
Make it about words you say every day.
- For work: "this", "that", "think", "thanks", "method", "month", "growth".
- For introductions: "the", "thank you", and any "th" words in your role or college.
- For daily life: "they", "there", "weather", "together", "health", "both".
Pick five "th" words you use a lot. Say each slowly with your tongue between your teeth. If you
catch yourself slipping to "t" or "d", pause and reset the tongue. Keep this small list handy.
Personal words stick faster than random lists.
Say it out loud (2-minute practice)
Do this once now. Go slow. Put your tongue between your teeth every time.
- Soft "th": say think, three, bath, math, mouth. Feel the air.
- Buzzy "th": say this, that, mother, they, weather. Feel the buzz.
- Minimal pairs: think/tink, three/tree, they/day. Hear the difference.
- Sentences: "I think this is the third month." "They are both healthy."
- Record yourself. Listen back. Did your tongue stay between your teeth?
If you want guided audio that shows the exact tongue position, the FirstWords English programme
breaks "th" down into small, friendly steps you can practise at home.
A gentle note on fear: "th" is the most-swapped sound in Indian English, and people understand
"tink" perfectly well. So if it slips, do not freeze. Just reset your tongue and say it again. You
are building a brand-new sound from zero, and that takes a few kind repeats, not stress.
Mini-FAQ
Will people understand me if I say "tink" instead of "think"?
Usually yes, from the sentence. But clean "th" makes your speech smoother and removes the small
guesswork for the listener. It is worth a little practice.
Why does my "th" sound forced?
You are probably pressing too hard. Keep the tongue light and the air gentle. Soft is correct.
How long until "th" feels natural?
With two minutes of daily practice, most people feel it getting easier within a couple of weeks.
Steady beats intense.
Is there one "th" or two?
Two. A soft airy one ("think") and a buzzy one ("this"). Same tongue position, the buzz is the
only difference.
Your next step
Pick three "th" words you say daily, "this", "think", "thanks". Say each five times today with your
tongue between your teeth. That is enough to begin. For a clear, guided path with audio, the
FirstWords English course is built for exactly this kind of practice.
