From our earliest childhood memories we can remember sitting in a classroom and going over a spelling list. Spelling is our language at its very basic stage and is an integral way for us to get our point across to others. When words are spelled incorrectly or used in place of other words, your meaning becomes distorted. This can lead to a great deal of confusion and embarrassment.
This is why it is vital to read over any papers you write and emails and text messages that you send. You do not want to mix up six for sex, bare for bear, or mail for male. Not only is this confusing to a reader, it also makes your work appear sloppy and unfinished. Getting in the habit of reading your work out loud a few times beforehand will allow you to catch any mistakes.
