Yaa “ي” as a Consonant
When “ي” is used as a consonant, it has the “y” sound, like in the word “yes.” For example:

Yaa Arabic Letter “ي” as a Vowel
“ي” can also act as a long vowel. In this case, it makes the sound “ee” like in the word “see.” For example:
- كتاب (kitaab) – meaning “book” (when the “yaa” is silent and only lengthens the vowel)
- مدينة (madeena) – meaning “city”
Common Words with “ي” (yaa)
Here are some common words in Arabic that include the letter “yaa”:
- يد (yad) – hand
- يمين (yameen) – right
- بنتي (binti) – my daughter
Arabic Letter Y “yaa” (ي) as a Moon Letter
In Arabic, there are sun letters and moon letters. The letter “yaa” (ي) is considered a moon letter. This means when the definite article “al-“ (the) is added before a word starting with “yaa,” the “L” sound in “al-” is pronounced clearly.
For example:
- اليد (al-yad) – the hand
- اليوم (al-yawm) – the day
In contrast, when a word begins with a sun letter, the “L” in “al-” is not pronounced, and the first letter of the word is doubled in pronunciation.

Yaa’ Al-Madd: Lengthening the Kasra Sound
In Arabic, vowels can be short or long, and the yaa’ al-madd (ي) is a long vowel that lengthens the short kasra (ـِ) sound. It transforms the short ‘i’ sound into a long ‘ii’ sound.
What is Yaa’ Al-Madd?
The letter yaa’ (ي) acts as a long vowel when it follows a letter that carries the short vowel kasra (ـِ). This long vowel, called yaa’ al-madd, stretches the sound of kasra from ‘i’ to ‘ii.’
Rules of Yaa’ Al-Madd:
- The letter before the yaa’ must have a kasra (ـِ) under it.
- The yaa’ al-madd does not have a vowel of its own; it simply lengthens the sound of the preceding kasra.
Example of Short vs. Long Vowels:
Vowel | Arabic | Transliteration | Sound |
---|---|---|---|
Short vowel | بِ | bi | ‘i’ (short) |
Long vowel | بي | bii | ‘ii’ (long) |
Examples of Yaa Al-Madd in Words
Word | Transliteration | Meaning | Explanation |
---|---|---|---|
بيتي | baytii | my house | The yaa’ al-madd extends the sound from ‘i’ to ‘ii’ |
كبير | kabiir | big | The yaa’ al-madd lengthens the short ‘i’ sound after kasra |
قميص | qamiis | shirt | The yaa’ al-madd changes the short kasra into a long ‘ii’ sound |
Why Yaa Al-Madd is Important
Lengthening vowels in Arabic can change the meaning of a word. For example:
- بِ (bi) means “with.”
- بي (bii) could indicate possession, meaning “my.”
Conclusion
The letter “ي” (yaa) is an important part of the Arabic alphabet. It can be a consonant, making the “y” sound, or a long vowel, making the “ee” sound.
Understanding its different forms and uses is key to reading and writing in Arabic. Whether it’s at the start, middle, or end of a word, “yaa” is versatile and essential in Arabic.
