Japanese people use んです(のです、んだ、 のだ)all the time, but explanations in course books are often quite lacking, so learners of Japanese just give up and don’t use this grammar, thinking that just using good old です everywhere is good enough. But if you keep avoiding it, you won’t speak natural Japanese, and it might even lead to some unpleasant misunderstanding.
ATTACHING んです:
んです (のです・のだ) can be directly attached to a noun, verb and い and な adjectives in plain form (普通形). But please note that when you attach it to a noun or a na-adjective of present affirmative tense, you need な as a bridge. For example, to attach んです to a noun 飛行機 you need to add な in between: 飛行機なんです, if you attach it to a na-adjective 簡単, it will become 簡単なんです. But other than that, you can attach んです directly to the plain form (普通形).
