For possessive pronouns:
my - the suffix is -im for words ending in a consonant:
bardað-ým, telefon-um, adres-im
or -m (your drop the vowel when you add it to word ending with a vowel):
araba-m, kedi-m, baba-m, anne-m, çanta-m
your - -in for words ending in a consonant:
bardaðýn, telefon-un, adres-in
or -n for words ending in a vowel:
araba-n, kedi-n, baba-n, anne-n, çanta-n
her/his - -i for words ending in a consonant
bardaðý, telefonu, adresi
or -si for words ending in a vowel (you add the buffer letter "s" )
araba-sý, kedi-si, anne-si, baba-sý, çanta-sý
our - -imiz for words ending in a consonant:
bardað-ýmýz, telefon-umuz, adres-imiz
or -miz for words ending in a vowel

their - leri - same for both words ending with vowel and consonant

When you add a personal ending to a verb or to express "to be" with a noun:
-im, -sin, -(no ending for he/she), -iz, -siniz, -lar
you always add the buffer letter
anne-yim - i am a mother
anne-sin
anne
anne-yiz - we are a mother (better anneleriz I think)
annesiniz
anneler
It can be a bit confusing at first, so I hope this helps a bit.
