Questions & Answers about O vefasız kişinin peşinden nasıl gittin?
Why is the ablative case (-den) used in peşinden gittin instead of the dative (-e) for direction?
While going to a destination takes the dative case, the idiomatic phrase peşinden gitmek (to go after / to chase) requires the ablative case (-den). Literally, it translates to going from the space behind someone.
How is the noun phrase kişinin peşinden constructed?
It is a standard genitive-possessive construction. Kişi gets the genitive suffix (-nin) to mean the person's. Peş (the space behind) gets the possessive -i, plus the buffer -n- and the ablative -den. Literally: from the person's behind.
Could I apply this lesson's target grammar and say O vefasız kişinin peşinden gittin o gidiş?
Absolutely, but it drastically changes the tone! Adding o gidiş makes the action irreversible. It would mean 'You went after that disloyal person, and we never saw you again.' In our sentence, gittin is just the standard past tense asking how or why the person did it.
Does vefasız only apply to romantic unfaithfulness?
Not necessarily. While it can mean romantically unfaithful, vefasız (from the root vefa, meaning loyalty or devotion) is broadly used for friends or family members who are disloyal, unappreciative, or who abandon you when you need them.
