Why does one add n to iru. Like in Lesson 9.1
ie....Itsu kara Toyko ni irun-desu ka?
I thank you in advance.

ケンさん こんにちは!
This is an excellent question. You will here this ending 〜んですか (~n desu ka) many times in colloquial Japanese. Maybe you'll start using it too! Let's just say that it's an informal version of the simple - のですか (no desu ka).
The ん (n) instead of の (no) in there makes the sentence sound softer and friendlier. There is no direct translation of this to English.
Try saying it yourself and note the difference - which sounds softer?
Tokyo ni iru no desu ka? (とうきょう に いる の ですか?)
Tokyo ni iru-n desu ka? (とうきょう に いるん ですか?)
The ending 〜んですか also kindly invites the listener to answer.
- Hope that helps!
Sayaka :P
