      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.

      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.

      [...] 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.

      Mârūf مَعروُف and majhul مَجھوُل, known and un-known. These Arabic terms are applied to the letters و wāo and ی ye. In Arabic the simple vowel sounds of these two letters are ū and ī, the sounds o and e are unknown in that language; so ū and ī are said to be mârūf, but o and e are majhūl. The majhūl sounds are sometimes called Âjamī or Persian.
