Use of も in 一緒に写真を撮ってもいいですか？


I understand the sentence "Can I take a picture with you?" in Japanese
overall, but I am a bit confused as for why one can use the particle も in the
sentence? What does it do?

Thanks for the help! C




It's part of the construction ～てもいいです, which expresses permission.

In this case, も isn't the same as the particle も meaning 'also' or 'same'.

Examples:

  * 新しくなくてもいいです。it's all right if it's not new/fresh. 
  * ビールでもいいですか。Will beer do? 
  * このいすを使ってもいいですか。May I use this chair?
