Demonstrative adjectives of kind (chenin, chenân)

To express "such a" or "this/that kind of", use the demonstratives چنین (this kind of) and چنان (that kind of).

Like basic demonstratives, they are placed directly before the noun and never take an Ezafe. Since you are typically describing "such a [noun]", the noun takes the indefinite suffix ی.

Pattern: چنین / چنان + [Noun] + ی

With Adjectives

When adding an adjective (e.g., "such a ridiculous story"), the adjective follows the noun with an Ezafe. The indefinite suffix ی moves to the end of the phrase, attaching directly to the adjective.

Pattern: چنین / چنان + [Noun] + Ezafe + [Adjective] + ی

Words Ending in Vowels

If the word taking the suffix ends in a vowel—like باورنکردنی (unbelievable) or ساختگی (fabricated)—the indefinite suffix is written as ای.
