Questions & Answers about Satıcı bu telefonun hiç bozulmayacağını iddia ediyor.
Since this lesson is about -(y)AcAkmIş, why didn't we use bozulmayacakmış here to express a reported claim?
Because this sentence uses a formal noun clause (a "that" clause) acting as the direct object of iddia ediyor. This structure requires the future participle -(y)AcAk with possessive and accusative endings (bozulmayacağını). If you wanted to use bozulmayacakmış, you would drop the formal structure and use a looser, indirect quote, like: Satıcı "bu telefon hiç bozulmayacakmış" diyor.
How do all the suffixes in bozulmayacağını break down?
It breaks down as bozul (break down) + ma (not) + y (buffer) + acağ (future, softened from -acak) + ı (its, matching telefonun) + n (buffer) + ı (accusative case). The final accusative -ı is required because this entire "its future not breaking down" concept is the specific direct object of the verb iddia ediyor.
Why does the word "phone" have the genitive (possessive) ending to become telefonun?
In Turkish noun clauses, the subject of the embedded action (the thing doing the breaking down) takes the genitive ending. "The phone" becomes telefonun, which links directly to the possessive -ı on bozulmayacağını. You are essentially saying "the seller claims the phone's not-breaking-down."
