What it means
بایو (bio) is the Persian word for the short self-description on a social media profile: the 150-character Instagram bio, the Twitter bio under your handle, the Telegram channel description. It is the line under the username where Iranians put their job title, a poem fragment, a Rumi quote, a phone number for business inquiries, or just a single emoji. The word is short for English bio (from biography), and it entered Persian with Instagram in the 2010s.
The Farhangestan suggests معرفی (mo’arrefi, introduction) or زندگی نامه کوتاه (zendegi-nāmeh-ye kutāh, short biography) for the underlying concept. Neither has any traction in social media contexts. Bio won the slot before any official alternative was proposed, and the word now sits naturalized in Persian, taking possessive endings (بایوش, bio-esh, his/her bio) and Persian verb collocations.

What goes in an Iranian bio
The genre rewards compression. A typical Iranian Instagram bio carries one or two of: a profession (دندانپزشک, dandānpezeshk, dentist), a city (تهران, Tehran), a poem fragment (often from Hafez or Forough), a Telegram channel link, a phone number for business, an emoji string. Diaspora bios add a second city in Latin letters (Tehran / Toronto). Activist bios since 2022 often include the date a friend was killed, or the name مهسا (Mahsa) in white-text-on-white as a coded marker. The form is small, the social signals it carries are not.
Where it comes from
Bio is a clipping of English biography. It became an interface label first on Twitter, then on Instagram, where the 150-character limit shaped the form into something different from a real biography, a kind of compressed self-pitch. Persian borrowed the interface label, not the underlying biography sense; the Farhangestan calques target the biography meaning and miss the social-media-specific version, which is part of why they failed to displace the word.
In our voice
Use بایو for any social media profile description. It is neutral, universal, immediately understood. The native معرفی still works in formal contexts (a speaker’s introduction at a conference) but not for the small box under your username.
