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. Domo arigato gozaimasu. ケン　べライル

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

どうま　ありがとう　さやかさん！　わかりました！ ケン　です
