Think about it: When you run a fever, for example, those three letters have a very different meaning than when you run a bath to treat it, or when your bathwater subsequently runs over and drenches your cotton bath runner, forcing you to run out to the store and buy a new one. There, you run up a bill of $85 because besides a rug and some cold medicine, you also need some thread to fix the run in your stockings and some tissue for your runny nose and a carton of milk because you’ve run through your supply at home, and all this makes dread run through your soul because your value-club membership runs out at the end of the month and you’ve already run over your budget on last week’s grocery run when you ran over a nail in the parking lot and now your car won’t even run properly because whatever idiot runs that Walmart apparently lets his custodial staff run amok and you know you’re letting your inner monologue run on and on but, God—you’d do things differently if you ran the world. Maybe you should run for office.
What's the most complicated word in your language? Is there one that can be used more than run?
