Pe (Persian letter)

Pe (پ) is a letter in the Persian alphabet used to represent the voiceless bilabial plosive ⟨p⟩.[1] It is based on bā' (ب) with two additional diacritic dots. It is one of the four letters that were created specifically for the Persian alphabet to symbolize sounds found in Persian but not Arabic, others being ژ, چ, and گ.[2]

It is used in Persian, Kurdish, Pashto, Balochi, and other Iranian languages, Uyghur, Urdu, Sindhi, Kashmiri, Shina, and Turkic languages (before the Latin and Cyrillic scripts were adopted).

Example of the letter's use on a street sign in Alexandria, Egypt, in French Rue Champollion and Arabic شارع شامپوليون.

It is one of additional common foreign letters that are sometimes used in some Arabic dialects to represent foreign sounds, it represents /p/ in loanwords and it can be substituted by ب /b/ such as in protein which is written as بروتين /broːtiːn/ or پروتين /proːtiːn/. In Egypt, the letter is called be be-talat noʾaṭ (به بتلات نقط [be beˈtælæt ˈnoʔɑtˤ], "be with three dots").
