Derek, whilst it was easy to read your post, that is only because our brains are trained to decipher what we know the word should be and have an understanding of sentence construction and grammar. However, if we didn't know the word in the first place or the sentence was not complete, then we wouldn't be able to work it out. Its vital that people learn how to spell properly in the first place and then learn how to put the words together in such a way as to convey the message that is intended.
