However, I won't understand what you mean unless I remember this
conversation.

I would much prefer "de-duplicate".

Of course, I would also much prefer "uniquify".

If a little French and Latin gets into this melange we call English, it'll

languages down alleyways to beat them unconscious and rifle their pockets
for new vocabulary." - James Nicoll
