Bound personal pronouns fulfill different functions depending on the word they come after.

Possessive adjectives

When bound pronouns come after a noun (phrase), they function as possessive adjectives:

پدرم
pedar-am
my father
مادرت
mâdar-at
your mother

If the preceding word ends in a long vowel, a -y- appears between the word and the pronoun:

صدایت
sedâ-yat
your voice
عمویت
amu-yat
your uncle

Object Pronoun

When bound pronouns come after a verb, they function as an object pronouns:

دیدمش
didam-ash
I saw him/her/it
فردا می‌بینمت
fardâ mibinam-at
See you tomorrow

After Prepositions

Bound pronouns are also used with prepositions, especially in spoken Persian:

برایمان
barâ-yemân
for us
ازم
az-am
from me
