Indefinite marker (yek … -i)

The Indefinite Marker (یک ... ـی)

When you want to talk about "a certain" or "a particular" person or thing without specifying exactly which one, Farsi uses a two-part indefinite marker.

To build this structure, place the word یک before the noun and attach the suffix ـی to the end.

If the noun ends in a vowel, the suffix changes spelling to connect smoothly. Words ending in a silent heh take an Alef (ای), while words ending in other vowels take an extra Yeh (یی).

When this "certain" noun is a specific direct object, the object marker را always comes after the indefinite suffix.
