Tha

Put the tip of your tongue between your teeth and blow softly: th, as in 'think' — just air, no voice.

Letter shapes

Tha in its four shapes

Arabic letters hold hands with their neighbours, so ث changes its look a little depending on where it sits in a word. Tap a shape to hear the letter.

Short vowels

tha, thi, thu: Tha with harakat

Add a little vowel mark and ث becomes a sound you can say. Fatha on top says a, kasra underneath says i, and damma on top says u. Tap each one.

Coral = fatha (a), blue = kasra (i), green = damma (u). How harakat work →
