This is the full sentence:


I think I was expecting something like です or よ.

I'm really confused about this だ.

  • Is your question about when to use だ vs です or do you simply not know what だ is?

だ is the informal version of です. 簡単だ has the exact same meaning as 簡単です, but the former is less formal.

For example, 私は猫が好きですよ has the same meaning as 私は猫が好きよ. But you would use です when talking to your 目上 (someone of higher social status) or in a formal situation, where you would use だ when talking to your friends

    I'm not a huge fan of framing it this way, since there are many situations where だ and です are not interchangeable, but maybe you were hoping to not confuse them with more details.
