Questions & Answers about Arkadaşım sözünü tuttu.
It breaks down like this:
- Arkadaşım = my friend
- sözünü = his/her promise or his/her word as the direct object
- tuttu = kept
So the sentence follows the common Turkish pattern subject + object + verb.
The base word is arkadaş, meaning friend.
The ending -ım is the first-person singular possessive suffix, so it adds the meaning my.
- arkadaş = friend
- arkadaşım = my friend
This is very common in Turkish. Instead of using a separate word for my, Turkish often adds a suffix to the noun.
Because the sentence is talking about a specific promise/word, not just promise in a general sense.
In Turkish, a definite direct object often takes the accusative ending. Also, söz here is possessed, because it is someone’s word/promise.
So sözünü includes more information than plain söz:
- söz = word, promise
- sözünü = his/her promise, as the object of the verb
In this expression, Turkish normally uses the possessed form because the promise belongs to someone.
