The letter س (Seen) is pronounced like the "s" in "sun" or "see". It is a voiceless alveolar fricative - air flows through a narrow channel created by your tongue near the upper teeth ridge. ☀ SUN LETTER (حرف شمسي): Seen is a SUN LETTER. When the definite article "ال" precedes it, the "l" ASSIMILATES into the س sound. Example: السَّمَاء = "as-samaa" (the sky) - you hear "as-samaa" not "al-samaa" LETTER FORMS: - Isolated: س (when standing alone) - Initial: سـ (at the beginning of a word) - Medial: ـسـ (in the middle of a word) - Final: ـس (at the end of a word) DISTINGUISHING FEATURE: Seen has THREE "teeth" - like a zigzag or waves (ـسـ). This is its most distinctive feature. - س (Seen) = three teeth, NO dots - ش (Sheen) = three teeth, THREE dots ABOVE Memory trick: "Seen is Simple (no dots), Sheen is Showered with dots" VOWEL MARKS (Harakat): - سَ (with Fatha): "sa" - like "sa" in "sun" - سُ (with Damma): "su" - like "sue" - سِ (with Kasra): "si" - like "see" - سْ (with Sukoon): just "s" - no vowel sound follows PRONUNCIATION NOTE: Arabic س is a "pure" s sound - never voiced like "z". English speakers sometimes accidentally voice this between vowels, but in Arabic it is always voiceless.
