"A lot of people ask me when I do a stunt, 'Jackie, are you scared?' Of course I'm scared. I'm not Superman." - Jackie Chan.
It's strange how the addition of a single letter can make all the difference in a word. Add an extra r to "scared" and you get "scarred". Not the same at all! Take an s away from "dessert", and you'll be stuck with "desert". Again, there's a big difference! Likewise, "lose" and "loose" are so similar, and yet two distinct words. And you wouldn't want to confuse "cloth" with "clothe" or "bath" with "bathe", either! Can you think of any more pairs of words where the difference in meaning hinges on a single letter?
