The letter Sin

سِين

Where it comes from

All 17 points

The tongue tip and lower teeth الأصوات الصفيرية

The tip sits just behind the lower front teeth and the air is forced through a narrow channel, producing a whistle. Ṣād, sīn and zāy share this whistle.

Also from here:زZayصSad

The short gold marks show which sides the letter joins to its neighbours.

Sin connects on both sides, so it has all four forms.

Same shape, different dots

These letters share one skeleton — only the dots tell them apart.
