is "thrice", but what about "four times"?
That's fierce. To research and answer that is. Apparently we can't do it more than three times. You'll just have to use "four times," "five times," and so on for anything more than thrice. What would four times be? Force? But the vowels in two and three got changed to "I" so firce? ( The words actually used to be the number with 'se' added, onese, twose, threese, but they morphed into easier things to get ones tongue and pence... uh, pen around. ( Besides onses, twose, etc. could easily be confused with the stages involved in playing jacks.) So fource? And how would we pronounce sixce? Its all a farce, it makes me tense just to think about. It wasn't very nince of you to cause me such head eightce.
