farther/further

Do I really need to go on "further" with this one? Okay, I will, since it's my appointed duty. It really is exhausting straightening you people out.

This one is simple. If you're dealing with a measurable distance (inches, feet, yards, miles, etc.), the correct use is "farther," as in, "Tom can throw the ball farther than me." Of course he can.

"Further" is a matter of degree. It can't be physically measured. "How much further do you intend to take your education?" "How much further do I have to explain this?"

This one is simple. I needed one that wouldn't take me 15 minutes to explain. For some reason, I'm short on minutes today, and I don't know why. It's really bothering me.

I'll see you a little "farther" down the road.
