My friend Panteha is of Iranian descent on her dad’s side. She recalls a phrase in Farsi that her dad would always use to begin stories or fairy tales he told her as a kid.

The phrase is, in the original Farsi:
یکی بود یکی نبود

It is transliterated as “Yeki bood yeki nabood,” which roughly translates to “once there was one and once there wasn’t one.” This phrase is used in essentially the same manner in which many english speakers use “once upon a time” to begin folk narratives, particularly tales. Although these phrases have different literal translations, they serve the same purpose: to establish the fantastical or fictional nature of a folk narrative.
