Questions & Answers about Ablam ve ağabeyim akşam bize gelecek.
Because Turkish usually shows possession with a suffix on the noun, not with a separate word like my.
- abla = older sister
ablam = my older sister
- ağabey = older brother
- ağabeyim = my older brother
So the sentence does not need a separate word for my.
The difference comes from how Turkish possessive suffixes attach.
For my, the suffix is basically -(I)m, but its shape changes depending on the noun.
If the noun ends in a vowel, Turkish often adds just -m:
- abla → ablam
If the noun ends in a consonant, Turkish adds a vowel plus m:
- ağabey → ağabeyim
The vowel in -im / -ım / -um / -üm follows vowel harmony.
