الدرس الثامن: تنوين زير
Welcome to Lesson 8 of Noorani Qaida. In this lesson, students learn Tanween Zer (Urdu: تنوين زير / دو زير, Classical Arabic: كَسْرَتَانِ / Kasratayn), which consists of two parallel diagonal strokes written directly underneath an Arabic letter (ـٍ).
Just as with Tanween Zabar in Lesson 6, Tanween represents the phenomenon of Nunation: phonetically sounding an unwritten, silent Noon Saakinah (نْ) attached to the end of a vowel. When a letter takes Tanween Zer, it produces the sharp closed sound "-in" (e.g. بٍ = بِ + نْ = "Bin").
In Lesson 6, you learned that Tanween Zabar almost always requires an Alif or Yaa written after it as an orthographic carrier (such as بًا or عَمَلًا). In sharp contrast, Tanween Zer NEVER takes a carrier Alif! It sits directly and independently below the base letter (e.g., بٍ, عِنَبٍ, عَمَلٍ). Never append an Alif to a letter with Tanween Zer.
Producing an accurate Tanween Zer requires two consecutive, rapid phonetic movements:
One of the most essential recitation rules in the Holy Quran is how to stop on a word ending with Tanween Zer:
Because Tanween Zer ends with a Noon Saakin, beginners must pay close attention to preserving the core nature of the base letter before merging into the "in" sound:
The practice section presents rich Quranic vocabulary demonstrating transitions between vowels and the Tanween Zer ending:
Starts with a deep middle-throat عِ with Kasra, followed by light نَ with Zabar, ending on بٍ with Tanween Zer. When stopping on Waqf, recite as "'Inab" with Qalqalah on the Ba.
Features four distinct syllables. Notice the ending is a Ta Marbuta with Tanween Zer (ةٍ). On Waqf, any Ta Marbuta always transforms into a quiet Haa Saakinah (هْ): "Nafaqah"!
A master test of alternating phonetics: light prefix بِ (Kasra), light سَ, heavy upper-throat خَ, and ending on heavy طٍ. Do not let the heavy letters pull the light letters heavy.
Practices throat حَ, dropping down to مِ, jumping to sharp Hamzah ئَ, and concluding with Tanween Zer on Ta Marbuta ةٍ. Each sound is clearly isolated and rhythmic.
The first stroke represents the original short vowel (Zer = 'i'), while the second stroke is a graphic symbol indicating the presence of an unwritten Noon Saakinah ('n'). Together, they instruct the reader to blend the vowel into a Noon sound ('-in').
In Arabic orthography (Rasm al-Khatt), Tanween Zabar historically changes into an Alif when paused upon (Madd 'Iwad), so an Alif is written to preserve that stopping pronunciation. However, Tanween Zer pauses on a Sukoon without lengthening, so no extra carrier letter is ever needed.

For young children or beginners practicing 15 to 20 minutes daily, lessons 1 through 8 typically take 2 to 3 weeks to achieve fluent, instinctive recognition and correct Tajweed pronunciation without hesitation.
