Japanese - Ask questions thread

Basically if you have a question about the language, ask it and fellow 4channers might see it and answer it for you.

To start it off. When an animate object (iru) dies, is it considered inanimate(aru)?

Is there some site or something similar that explains the radical (bushu?) system? Like how all kanji with this and that kanji have this and that reading, and such? A list over all radicals would be nice too.
