Don, no doubt that "oftentimes" is a correct English word. To my feeling, it does not sound profound, but somewhat finicky, as if it were slightly archaic. As I said, I may be wrong.

Neologism: a scientific term, not profound, just exact. "Newly coined word" may do, but is lengthy. (I cannot claim my posts to be always as readable as possible; please grant me pardon as a non-native-speaker. However, if you catch me dressing up shallow thoughts, do not spare me your criticism by any means!)
