First of all, for you skeptics out there, “whelmed” is really a word, though we don’t use it because it doesn’t seem to have any relationship to it’s more popular off-spring, Over- and Under.
1. to submerge; engulf.
2. to overcome utterly; overwhelm: whelmed by misfortune.
So overwhelmed implies misfortune? How does that work when used as “Overwhelmed by gratitude, joy, or excitement?” Are those things actually misfortune in disguise? Or is it the oncoming waters of drowning and submersion that carry the negative implication?
Sometimes, the weird ins and outs of our peculiar language leave me agape. That’s right. Agape. And what do you want to make of it, eh? I’ll whelm you if you diss me, girlie!
