Etymology
Origin of impossibility
1350–1400; Middle English impossibilite < Late Latin impossibilitās. See im- 2, possibility
Explanation
An impossibility is something that can never, ever happen. Eating ice cream without getting a stomach ache afterward is an impossibility for people who are lactose intolerant. You might start to suspect the impossibility of finding an affordable apartment in New York once you start looking for one, or fear the impossibility that you'll ever pass your French class if you struggle with conjugating verbs. When something's impossible, it can't happen or exist, and an impossibility is impossible. Both words come from the Latin impossibilis, "not possible," from the roots im-, "not," and possibilis, "that can be done."
