Questions & Answers about Yolda arkadaşımı gördüm.
The -da here is the locative case marker, meaning “in,” “on,” or “at.”
• yol (road) + -da → yolda = “on/along the road.”
Vowel harmony applies: o is a back vowel, so the locative ending is -da (not -de).
Break it down:
- arkadaş = “friend”
- -ım = first-person singular possessive → arkadaşım = “my friend”
- -ı = accusative case marker for a definite/direct object → arkadaşımı = “my friend” (as a specific person I saw)
So arkadaşımı literally combines the possessor suffix (-ım) with the object-marker (-ı).
