I was wondering if Hitherto is correct in the following phrase: Hitherto, the necessary component that excites and triggers that unyielding intrigue is (or has been) absent in the financial world that I am (or have been) acquainted with. I believe that "Up until now" would be just as fine, but for purpose of concision I chose hitherto. I was also wondering, is this word somewhat dated? Is there a greater tendency to use "up until now, Until now, etc..."? Thanks in advance. D.
