Because the verb “bakmak” (to look) does not take a direct object; it requires the dative case. In Turkish, the verb “bakmak” takes the dative suffix (-e / -a). So when you look at someone or something, you use the -e / -a ending. bana = ben + -a (dative case) beni = ben + -i (accusative case) The verb “bakmak” takes -e / -a, not -i. ❌ beni bak (incorrect) ✅ bana bak (correct)
