I never have difficulty using "there" or "their" correctly. Always remembering that "their" shows ownership (that's how I think of it) and "they're" is a combined "they" and "are" not showing ownership.
But "break" and "brake" and "effect" and "affect", very different story.
My writing looks like Jr. high sometimes when I get these all messed up.
Mama tells me that now they don't even do sentence diagramming in school. Holy Cow Batman!
How do they learn it than, what is correct word usage? I did diagramming and hated it, but did it well and look at me now..still screw it all up!
