*Japanese Word of the Day*
/nanda. omotteta-yori kantan jan/
Oh it's no big deal, it's easier than I thought.
*なんだ /nanda/ You say it when you don't satisfied with the result, or it's not good enough as you expected. It is also pronounced like なーんだ/naanda/ with a disappointed tone.
*思ってたより /omotteta yori/ than you expected
If you want to say as negative form, you have to say 思ってたほど.
(She was) not as cute as I expected.
It wasn't as fun as I expected.
*簡単 /kantan/ easy ⇔ 難（むずか）しい /muzukashii/ hard, difficult
*じゃん /jan/ We put it at the end of the sentence to emphasize it. Or it's used to confirm the positive. Well, people in the west part of Japan (especially in Kansai area) usually say やん /yan/ instead of じゃん.
Learning a foreign language isn't easy, but it's interesting. Right?：）
