Ms. BoxJam: From whence came this pile of potato chips?
BoxJam: Tsk... "Whence" doesn't require "from," as it's already implied.
BoxJam: It follows a pattern, common in Middle English, traces of which are still in our modern language. "Wh-" is the question form of a word; "h-" is "this one"; "th-" is "that one":
[[A table shows the following paradigm:]]
whence: from what point? / hence: from this point / thence: from that point
where: what place? / here: this place / there: that place
whither: to what point? / hither: to this point / thither: to that point
wherefore: for what reason? / herefore: for this reason / therefore: for that reason
wherein: in what? / herein: in this / therein: in that
BoxJam [[sitting by the potato chips]]: So, just as you'd never say "from thence," there's no reason to say "from whence"...
Ms. BoxJam: I'm sorry... from now on I'll only say "from" when asking "from which jerk" something emanated...
BoxJam [[munching happily on a chip]]: Which jerk are you talking about?
Ms. BoxJam [[pointing at him]]: Hich one.
