Level: intermediate
characteristics
tj-028
Itbaq: Tongue presses against upper palate — produces maximum heaviness.
4 letters: ص ض ط ظ — these combine both Isti'la and Itbaq, making them the heaviest letters.
Infitah: No tongue-palate contact — remaining 24 letters.
Common error: Not fully pressing for Ta (ط) and Dad (ض).
