N5 grammar
〜んです
ndesu
Explaining the situation
Formationplain form + んです (noun / na-adjective + なんです)
んです frames a sentence as an explanation of what is going on rather than a bare fact. You reach for it giving a reason, asking for one, or setting up a request. Without it, an answer to why can land abruptly.
