No, actually, you picked a bad example.

Their is pronounced "thur"

There is pronounced "ther"

They're is pronounced "theyur"

But the to, too, two example is right on.

Your original example is confusing for most people becasue they've never been taught pronunciation.

Another example of dumbing down of the common man. How do we improve on test scores? LOWER THE STANDARDS. Brilliant. Meanwhile the Chinese, Indians and even the Russians are leaving us in the dust. Most Europeans learn two extra languages aside from their native tongue,,,, in grade school.
