Vowels in Arabic: Long Vowels and Diphthongs

A long vowel in Arabic is exactly what it sounds like. It’s a lengthening of the short vowel. It is exactly like the short one but held longer in pronunciation. This is usually accomplished in English by using a double letter just like in the words “loop” and deep”. There are three long vowels: ā, ū, and ī written medially as ‘alif ا, wāw و and yā’ ي, respectively. Occasionally, ā is written using a yā’ without dots (ى) rather than an alif. This always happens at the end of a word and is called ’alif maqsūra as in على (alā) which means “on”.

– ā: (long a) is pronounced like a short “a” in ordinary environments but held for a much longer duration, some say “twice as much time”.
– ū: (long a) is pronounced like a short “u” but held for a much longer duration, like “oo” of “moon”.
– ī: (long i) Similar to the “ea” in “beat”. In velar environments, the quality is significantly “clouded”-rather like “ea” in “peal”.

Diphthongs in Arabic:
Diphthongs in Arabic are vowel sounds consisting of two parts, a short vowel and a consonant. the diphthongs “ay” and “aw” are written ـَ ي as in “بيت” [baitun] a “house”, and ـَ و as in “خوف” [khaufun] Arabic name for “Fear”.

  1. Hello and thank you for providing this forum. Your explanation of Arabic dipthongs is what I expected but I keep wondering about a third dipthong, namely what in English is ‘I’. This is indicated as aI, the IPA symbol, in dictionaries. I’ve only been studying Arabic for a short time, but I’ve sometimes come across this sound. Perhaps it is some local variation of speech. What do you think?

  2. Salam Alejandro,
    I hope it’s not too late for my answer. At first I didn’t know how to address your question, but after talking to an Arabic teacher, it was all clear to me that you were referring to the “waw” as in the Arabic word “Salaah”, “Zakaah”, etc.
    You’re only going to see that “waw” in Qur’an and some old books that use a specific Arabic Writing Style called “Ar-rassm al-Utmaani” or “al-khat al-Utmaani”. Back in the days and early version of the Qur’an, there were many writing styles among them the “Utmaani” style, these styles didn’t use “Shakl” and “Tanqiit” (Vowels & dots). people were able to understand Arabic that way. but now a day, things are little bit different.
    I hope I was able to answer your question.
    Salam 🙂

  3. Selams to you all.

    I can undertstand Alif maqsurah. But in some words, there is a dagger Alif above a waw saaakin, And we still read as a long alif. Why there is a waw there. For example in the word: Salaah ( sad, lam (long with a dagger Alif), waw and teh marbuutah.

    Why waw?

    Shukran lekum :))

  7. Nice job,site looks professional and the information is valuable but wanted to highlight that there are additionally short vowels which are the diacritics(altashkeel) we use in Arabic. I’m an Arabic research in the field of speech and language pathology. Jazzak allah kear
