[Grammar] It is also impossible to know everyone's true identity online.

[newkeenlearner]

Is my analysis OK? Does"online" relate to the verb "know" ?

Main sentence: It is also impossible to know everyone's true identity online.

Revised version: It is also impossible to know everyone's true identity when they are online.

Someone doesn't have to actually be "online" (connected to the internet at that moment) for the rest of the statement to be true. They simply have to have an online presence.

I got it. [STRIKE]teacher.[/STRIKE] Thank you. So can we say (no question mark here) "It is also impossible to know online everyone's true identity"?

No. That doesn't work. There isn't really a short way of saying it. "It is impossible to know the real identity of anyone/everyone on the internet".
