parayı
"Parayı" means "the money" in English.
In this sentence, 'parayı' is used as the direct object of the verb 'koydum' (I put). It is in the accusative case, marking it as the specific item being acted upon.
Parayı masaya koydum.
I put the money on the table.
Here, 'parayı' again appears in the accusative case, indicating the money as the thing to be spent, making it the object of the action 'harcamak' (to spend).
Parayı harcamadan önce düşünmelisin.
You should think before spending the money.
In this usage, 'parayı' is the object of the verb 'kazandı' (earned), specified as the item gained by the father.
