Forming the past stem

Infinitives as Verbal Nouns

Before building past tense verbs, it helps to recognize Farsi infinitives. Every Farsi infinitive ends in either تن or دن.

Aside from being dictionary entries, infinitives are frequently used in sentences as verbal nouns. This is equivalent to the English "-ing" gerund (like "cooking" or "arriving").

Extracting the Past Stem

To conjugate any verb into the past tense in Farsi, you first need the past stem. The rule for finding it is simple and completely regular for every verb in the language.

Simply take the infinitive and drop the final ن.
