When someone says something to me and I don't really understand the meaning, how can I respond?
What is the difference between:
- 何て言う意味ですか。
- 何て言うことですか。
- どう言う意味ですか。
I might be wrong, I might mix everything from what I've heard, read, seen.
Environment: Polite, formal, informal, anything is fine.
Extra question, how to say it in keigo?
