ASCII Character ئArabic letter Hamzah on ya
Hamza (Arabic: همزة hamzah) (ء) is a letter in the Arabic alphabet, representing the glottal stop [ʔ]. The hamza above ya ⟨ئ⟩ is known as a "housed hamzah" (Malay: hamzah berumah), and is most commonly used in Arabic loanwords. It is also used for words which repeat or combine "i" and "é" vowels like چميئيه (cemeeh meaning "taunt") and for denoting a glottal stop in the middle of a word after a consonant such as سوبئيديتور (subeditor). More commonly, however, it is used for denoting a schwa after the vowels "i", "é", "o", and "u" such as چندليئر (chandelier).
