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)?

what's しやがって, as in, 無茶しやがって?

If it's slang and it cut off some stuff, what's the original? If that's just what it is, can you break it down for me?
