Fingilish, Pinglish, Penglish or Fargelisi (a portmanteau word formed from Persian + English, or Farsi + English) is the way Persian words are written using the Latin alphabet (as opposed to the Persian alphabet), or generally the casual romanization of Persian words popularized after computers, emailing and online chat became ubiquitous. This type of writing is commonly used in online chat, emails and SMS. It developed and spread due to a former lack of software supporting the Persian alphabet, and/or due to a lack of knowledge about the software that was available. Although Persian writing is supported in recent operating systems, there are still many cases where the Persian alphabet is unavailable and there is a need for an alternative way to write Persian with the Latin alphabet.
Initially there were no strict rules for conversion into Fingilish or how words were romanized, and the way of writing Fingilish varied greatly by accent. More recently a standard called Desphilic script script has been introduced, which standardizes the concept and usage of a Persian-Roman alphabet. Desphilic script can be used to officially transliterate Persian and related dialects into a character set suitable for ordinary English keyboards, and also accepts UniPers characters (Â, Š, Ž). Unipers is another standard, defining an extended Persian-Roman alphabet for Persian language.
The following table contains some examples of romanized Persian words and the ways they are used by Persian chat users.
There is software to help transliterate from Fingilish to Persian and vice versa. For example, Google has added a page to its Google Transliteration set which can be used to transliterate from Fingilish into Persian script. There are also communities and message groups for Fingilish on some famous websites like Facebook.
Social Acceptance 
Writing Fingilish is often considered bad style among Persian speakers, and is confined to (very) informal communication. It is considered to be highly inappropriate to write official or polite messages in Fingilish; this reaches the point that, when there is no way to write the Persian alphabet, communication occurs directly in English rather Fingilish. Recently its counterpart Enersian has arisen and is being used in Iran in SMS.

There also exist trials and standards to help Fingilish users and provide them a more convenient way to write Persian using roman alphabet. Because some Persian alphabet letters do not exist in English, a Persian Keyboard (PArsi keyboard or PArsic keyboard) has been invented which provides Fingilish users with additional characters like [ ä Ä, š Š, ğ Ğ, ž Ž, ü Ü, ö Ö, ķ Ķ] which can be used as counterparts for [آ ش ق ج ژ او خ ].
A Persian poem in Fingilish 
Del iy ke qeyb namAy ast o jAm e jam dArad
