Yes AJT. I wuz writing while you posted. From the principle definition of both words, I would be very loath to use them interchangably. As you saw from my last post, I saw it in Chambers. My motto, if in doubt - don't use it.
I cannot, for the life of me, see how "deduce from evidence or reasoning" = "indicate by suggestion". But, if the debate has gone on for centuries, it's unlikely to be settled here. Eh? Have a good day
