Learn Turkish: Doktor bana yeni bir kliniğe gitmemi önerdi. - The doctor advised me to go to a new clinic.

In Turkish, indirect requests use a short verbal noun (the -me or -ma suffix). You attach a possessive suffix to show who is doing the action, followed by the accusative case. So gitmemi breaks down as git-me-m-i (go - action - my - specific object). Literally, the doctor suggested my going.

Why do we need the accusative -i at the end of gitmemi?

The verb önermek (to advise or suggest) needs a direct object. What did the doctor suggest? He suggested the action of going to a new clinic. Since gitmem (my going) is the direct object of his suggestion, it takes the accusative case -i.

Why is it bana (to me) instead of beni (me)?

In English, we just say the doctor advised me, but the Turkish verb önermek requires the dative case for the person receiving the advice. You are suggesting an action to someone. Therefore, we use the dative pronoun bana.

Why does klinik change to kliniğe?

When you add a suffix starting with a vowel to a word ending in k, the letter k usually softens to a ğ. Here, we add the dative suffix -e (to) to klinik, making it kliniğe (to the clinic).
