क ख ग घ in Tamil: how to say the Hindi sounds Tamil doesn't write

Why these sounds are hard for Tamil speakers

Tamil does have the “g” sound — you say it in மகன் (magan) and தங்கம் (thangam). But Tamil decides the sound by the letter's position, so one letter is enough, and a Tamil ear learns to treat “k” and “g” as the same thing.

Hindi gives each sound its own letter, and changing it changes the word: पल is a moment, फल is a fruit. So the job is not to learn new sounds from nothing — it is to notice two differences your mouth already makes.

The four sounds of each row

Read the table across: plain, add breath, add voice, add both. That is 20 letters with one rule. (Each row also ends with a nasal — ङ ञ ण न म — which Tamil already has: ங ஞ ண ந ம.)

Test 1: the paper test for breath

1. Hold a thin strip of paper, or your palm, about three fingers in front of your lips.
2. Say प (pa). The paper hardly moves.
3. Now say फ (pha), with a small “h” after the “p”. The paper flutters.
4. Try क / ख, त / थ and च / छ. The breathy letter always moves the paper more.

Test 2: the throat test for voice

1. Put two fingers lightly on the front of your throat.
2. Say a long क… then a long ग…
3. With ग you feel a buzz. That buzz is the voice. ज, ड, द and ब buzz the same way.
4. For घ, keep the buzz and add the breath from Test 1: “g-h-a”, said quickly as one sound.

Word pairs: hear the difference

Tap 🔊 on both words of a pair, then say them aloud yourself. If they sound the same to you, use the two tests above and try again.

How to write these sounds in Tamil letters

Tamil has no letters for them, so learners use a few conventions. Karu AI writes ख as க்ஹ, ग as க (ga) and घ as க்ஹ (gha). Some Tamil books use small numbers instead: க, க², க³, க⁴ for क, ख, ग, घ. Use whichever your teacher uses — but learn to read the Hindi letter itself as soon as you can.

One pair Tamil already gets right: ट = ட (tongue curled back) and त = த (tongue on the teeth). Keep that difference in Hindi.

A 5-minute daily practice

1. 1 minute: read one row of the table across, slowly — क ख ग घ.
2. 2 minutes: the paper and throat tests on that row.
3. 2 minutes: three word pairs, aloud, twice each.

Do one row a day and you will have practised all five in a week. Then move on to reading practice with real words.
