Return no longer means return
I assume this train has left the station, but there are so many people now who say "return back" when "return" by itself is quite adequate (given that it means to go back.)
I often hear this on TV - the source of most misuses and distortions of the English language. 50 years from now, I predict, most people will be speaking a kind of pidgin English with hugely reduced vocabularies and the grammar of six-year olds. Fortunately I won't be around.
