I had a weird experience with the word "copy". We use MS Exchange and Outlook, and all the email is stored on the server. Outlook is the client that views the email on the server.
A user was having some problems with it, and I said something like "well, it's just fixing it's copy of the email."
She then asked if she could delete the emails, since there's a copy on the server. I said, "no, if you do that, it'll delete it on the server too." She then said, "so it's not a copy."
