I am sorry for asking such a basic question, but I just starting learning Japanese, and was wondering, when are U and I silent?
I have heard 'masu' and 'desu' and 'arashi' pronounced 'mas' and 'des' and 'arash' but never 'haiku' pronounced 'haik' and stuff like that. I have a Japanese language book that says that the u's and i's are sometimes not clearly pronounced, but it fails to say when, and another Japanese book says nothing about the silence of u's and i's. Can anyone clarify this for me?
