majhul

A class of vowel used in various Arabic script languages, including Persian, Kurdish, and Urdu, among others:

The New Persian [of Iran], as is well known, has confused in many words the majhūl (' unknown [to the Arabs]' =Persian sounds) vowels ē, ō with the ma'rūf ('known [to the Arabs]'=Arabic sounds) vowels ī, ū. The Judaeo-Persian and the Baluci, like the Indian pronunciation of New Persian, maintain clearly the original distinction between the majhūl and the ma'rūf vowels.

The majhul sounds o and e are still preserved in the Persian spoken by Afghans and Indians, but they are now unknown in Persia.

A class of vowel used in various Arabic script languages, including Persian, Kurdish, and Urdu, among others:

[...] there are two kinds of Yā in Persian, namely, the Ma'rūf and the Majhūl. The Ma'rūf or known Yā is the Yā which occurs in such words as رقیب, تیر, شیر (milk), دید, پیل etc., while the Majhūl or Unknown Yā occurs in words such as خویش, تیز, شیر (lion), سپید etc.

If the stem ends in either ی-ma'rūf (i) or ی-majhul (e), the letter ج is inserted, for the sake of euphony, between the stem and the termination: e.g., from پینا to drink, we have پینجیئے, پیجیو, and پیجییگا, from دینا we have دیجیئے, etc.

A conditional allophone of a vowel phoneme that appears in proximity to certain guttural consonants.
