Courtney's Grammar and Spelling Pet Peeves

Ah, you knew this was coming eventually, didn't you? As much as I harp on accurate spelling and correct grammar, and since I've spent part of the last four years teaching conversational English, it was inevitable that I'd come to the point of needing to make a post about this ever-popular subject. *insert weary groans here* ;oD

Language is a beautiful, amazing, wonderful thing that God came up with. It is the basis of everything we do; without language--whether spoken, written, or signed--human communication and interaction would be impossible. Language carries the essence of our human cultures; you will never completely understand a culture until you know its language.

Communication is the foundation of positive human interaction. Conversely, lack of communication is the cause of our every misunderstanding. That's why I'm so interested in language, and that's the basic reason why I'm often so particular about spelling, grammar, and expression.

So, without further ado, I give you my list of grammar and spelling pet peeves. This list is subject to revising and to growth, so check back periodically if you're interested. This is my collection of frequent grammar and spelling errors that I have observed (and sometimes made) personally; some of them seem to be habitual errors that many native English speakers make.

And not to worry--I'm not anticipating any feedback on this one. ;o)
