Haa هَاء
A soft 'h' as in hat, from deep in the throat.
Its shapes
Trace it with your finger
👄 Where the sound comes from
The throat: its bottom part · ه
The deepest place, nearest the chest.
⚖️ Don't mix it up with
- ح
Ḥaa
A strong, breathy 'h' from the middle of the throat, like fogging a mirror.
Say Haa and the other letter one after the other, slowly, and feel the difference. A teacher can check you.
