Yes : ஆம் or ஆமாம் Aam or Aamaan
Ok : சரி - Sari ( Sometimes sounds like Chari )
No : இல்லை - Illay
Pain attention to long and short vowel sounds, One tip is to you greatly exaggerate the length of your long vowels. For example, to say "yes" in Tamil you would say "aama", but it would not be wrong to pronounce it 'aaaaaaaaaama'.
ஆமாம் aamaam is used when you are asked a question.
Usage examples :
Should you use Aamaan in the phrase '' Yes, you can take the chair '' ?
No! the Aamaan meaning is like '' Yes,true! ''
You should use : எடுத்துக்குங்க * Literally take it *
