Questions & Answers about Ben kitabı gerçekten bitirmedim.
How do the negative and past tense suffixes combine in bitirmedim?
It breaks down as the verb root bitir (finish) plus the negative suffix -me, the past tense suffix -di, and the personal suffix -m (I). Because of vowel harmony, the front vowels in bitir mean we use -me and -di rather than -ma or -dı.
The word for book is kitap. Why does it change to kitabı here?
Because the book is the specific object being finished, it takes the accusative case suffix -ı to mean "the book". When a suffix starting with a vowel is added to a word ending in "p", the "p" softens to a "b". So, kitap becomes kitabı.
Why does gerçekten come right before the verb?
In Turkish, adverbs like gerçekten (really) usually go immediately before the verb they describe. This highlights exactly what part of the sentence is being emphasized as true.
Is the word Ben (I) strictly necessary in this sentence?
No, you can leave it out and just say Kitabı gerçekten bitirmedim. The -m at the very end of the verb already tells the listener that "I" am the one who didn't finish it. Using Ben here just adds a little extra emphasis.
