For Extra Credit -- Tell me how you can know when to use each of these words.
Farther vs. further? You should use "farther" whenever you’re dealing with actual distance: “My dad can throw a cow pie farther than your dad.” Use "further" when you’re talking about something that doesn’t have a physical, distance-based measurement to it: “My dad would have gone further in life, if he didn’t have such a disgusting hobby.”
