Also the final or isolated form of ي in the Nile Valley, when typed on electronic devices, which looks similar in shape to the Persian ی in its final or isolated form.
Only written in the final position, transliterated ā. Called أَلِف مَقْصُورَة(ʔalif maqṣūra, literally “shortened alif”) or أَلِف لَيِّنَة(ʔalif layyina, literally “flexible alif”). In the rare case of a rasm version of Quran, it is a version of yāʾ.
the letter is sometimes spelled as ی in the final position. This was the original form of the letter in final position for both of -ī and -ā, before the creation of ي in the late nineteenth century in the Levant. The continued use of this form long after the creation of ي may be due to Ottoman influence in Egypt where the newer Arabic form was rare and this form was the prevalent. Compare that in Egypt, the Arabic alphabet letters are (still) named based on the Ottoman convention, a practice now almost exclusive to Egypt and Sudan.
Electronically, the similar shaped ى is used and/or interchangable with both the dotted and undotted versions.
Represents the back vowel phoneme /ə/, unless a small ء (hamza) was placed in the beginning of the word. In Kazakh the Hamza marks that all vowels in the following word are fronted. If ى is the initial letter of a word and is representing a front vowel, it is combined with the hamza and the variant ٸ is used.
