I was reading a letter from Warren Weaver to Norbert Wiener (1949), and this sentence drew my attention:
One naturally wonders if the problem of translation could conceivably be treated as a problem in cryptography.
What's the point of adding conceivably? E.g. couldn't we simply say:
One naturally wonders if the problem of translation could be treated as a problem in cryptography.
Use the adverb conceivably when you're talking about something that is believable or possible. You could say, for example, that you'll conceivably still be on time to work after oversleeping, especially if you skip breakfast.
Doesn't "could" already convey this meaning of possibility, making the expression "X could conceivably ..." redundant? Or is it a valid way to emphasize on the possibility aspect of the claim?
