In today's post on her blog (The Grammarphobia Blog), Pat O'Connor writes: "By chance, as we were researching another question, we recently happened upon the reference you mention."
Isn't "by chance" redundant? Doesn't "happen on/upon" mean "discover by chance"?
happen upon - definition of happen upon by the Free Online Dictionary, Thesaurus and Encyclopedia.
Dictionary says "to find unexpectedly."
I agree that it is basically redundant.
