The Arabic letter س (sīn) is the 12th letter of the Arabic alphabet. In fact, it represents the /s/ sound, just like the s in the English words sun, see, and snake. Therefore, it is one of the easiest Arabic letters for English speakers to pronounce because the sound is very similar.

How to Write the Letter س

Like most Arabic letters, س changes its shape depending on its position in a word.

Writing Steps

1. Begin with a short stroke on the right.
2. Draw three small upward curves (teeth).
3. Finish with a smooth curve that extends slightly to the left.
4. When connected to another letter, the final curve joins the next letter naturally.

Tip: The three “teeth” are the main feature that makes س easy to recognize.

How to Pronounce س

The letter س always makes a clear, light “s” sound.

The /s/ Sound in English

• It is voiceless, meaning your vocal cords do not vibrate.
• Place the tip of your tongue close to the ridge just behind your upper front teeth.
• Push air through the narrow gap to produce a gentle hissing sound.

It sounds like:

• s in sun
• s in see
• s in snake

Unlike ص (ṣād), س is not emphatic. Keep your tongue relaxed and do not deepen the sound.

س with Short Vowels

Practice reading these aloud several times.

س with Long Vowels

Remember to hold the vowel slightly longer than the short vowel sounds.

Common Words with س

Minimal Pronunciation Comparison

Learning to distinguish similar Arabic letters is important.

Practice saying:

• سَ سَ سَ
• سِ سِ سِ
• سُ سُ سُ

Then compare:

• سَ – صَ
• سَ – زَ
• سَ – شَ

Common Mistakes

• Pronouncing س like ز. Remember that س is always /s/, never /z/.
• Confusing س with ص. Keep س light and relaxed.
• Turning س into ش by adding a “sh” sound.
• Forgetting the three characteristic “teeth” when writing the letter.

Practice Exercise

Read these syllables:

• سَ
• سِ
• سُ
• سَا
• سِي
• سُو

Now read these words:

• سَمَك
• سَلَام
• سَيَّارَة
• سُوق
• سَاعَة

Finally, try this simple sentence:

سَامِي ذَهَبَ إِلَى السُّوقِ.
Transliteration: Sāmī dhahaba ilā as-sūqi.
Meaning: Sami went to the market.

Summary

The Arabic letter س (sīn) represents the light /s/ sound, just like the English s in sun. It has four written forms depending on its position in a word, is recognized by its three small “teeth,” and connects to both the preceding and following letters. Mastering س early will help you read and pronounce many common Arabic words accurately.
