Questions & Answers about Zavallı ailenin her şeyi kaybettiği trajik.
Why doesn't kaybettiği have a case marker like -ni or -ne at the end?
Because the entire clause Zavallı ailenin her şeyi kaybettiği (that the poor family lost everything) acts as the subject of the main sentence. In Turkish, subjects take the nominative case, which means no case suffix is added. You just attach the third-person possessive ending -i to the -dik participle and stop there.
Why is the subject of the clause, aile (family), in the genitive case as ailenin?
When you create a factive clause using -dik or -ecek, the subject of that specific action takes the genitive case, and the verb takes a matching possessive ending. You can think of ailenin ... kaybettiği literally as 'the poor family's losing'.
Since the clause acts like a noun, why does her şeyi still take the accusative case?
Even though kaybettiği turns the whole phrase into a noun for the main sentence, it still acts as a verb inside its own mini-sentence. Because her şey (everything) is the specific direct object of the verb kaybetmek (to lose), it requires the accusative ending -i.
Why are there two t letters in kaybettiği?
