Questions & Answers about Bence sınav zor değildi.
How do we get bence from ben (I)?
The suffix -ce (or -ca) translates to "according to" or "in the opinion of." When you attach it to ben (I), it becomes bence (in my opinion). You can also do this with sen (you) to make sence (in your opinion).
Why is the past tense ending -di attached to the word değil (not)?
In Turkish, değil is used to make negative sentences with adjectives or nouns. To talk about the past ("was not"), you attach the past tense ending directly to değil, making it değildi. If it were present tense, it would just be değil.
Why does değildi come after zor?
Do I need to say o (it) before zor değildi?
No, you don't need an extra word for "it". The subject is already stated as sınav (the exam), so the literal structure is simply "the exam hard was-not".
