What does this で in でいいですか do?


アンドレアスさん、でいいですか？

"Are you well, Andreas?"

Obviously this で doesn't prevent me from understanding the sentence. However,
what does it add to the sentence?




This で is a sort of situation/method/means marker, and the sentence is
confirming アンドレアスさん is the right name, choice, etc. "Is it okay if I used
Andreas-san?" is a terrible translation but should help you understand the
gist of the sentence.

For example, this is used in the following situations.

  * You're seeing bad handwritten characters, and want someone to confirm if it really reads "Andreas".
  * You're discussing with your boss who to hire, and you're about to conclude you will hire Andreas.
  * Your team has a bothersome task, which you have to assign to someone. You're trying to ask Andreas if he can do it for the team.
