About ~んです・のです

のです is a construction with several different forms, each meaning roughly the same thing. This expression behaves similarly to and です by themselves (asserting that something is true). However, the addition of の strengthens the relationship being highlighted. Due to this, it will come across a bit like 'it is a fact that (A)' in English.

In these sentences, we can think of the , or as simply adding emphasis to the statement. Due to adding emphasis, this expression will be heard very frequently in explanations.

Caution

There is no real difference between and . Only is considered 'correct Japanese', but evolved to make things easier to say. is the most common form in spoken Japanese, and the use of could be considered a bit formal, or 'stiff'.

While both the and です forms are equally as natural, only the です form will be used if adding to the end ~んです. This construction shows that the speaker is looking for an explanation about something.

              Hey @PapaYeti !

              The が you are referring to is this!

              When this が is used at the end of a sentence, it means that there is more information that exist, but the speaker is omitting it due to the information being very obvious.

              For example, the sentence 手紙を送りたいのですが has the nuance of, ‘I would like to send a letter, but…(I’m not sure how to send letters/I don’t know where to drop the letter off)’. The extra information will of course be different depending on the context.

              I hope this answers your question!
