Yes, English spelling is challenging.
No, it is not so difficult that native speakers have any excuse to misspell the common words they use.
7 Steps to Good Spelling is an easy-to-follow handbook for readers who are tired of making basic spelling errors in their online communication or business correspondence.
Most people who self-identify as “bad spellers” were never taught the basics of the English sound code. After all, for several decades now the teachers’ colleges have been promoting a program of reading instruction that teaches English words as if they were pictures, not groupings of sound symbols. Only recently are the high muckety-mucks admitting that an alphabetic language is best taught with phonics.
The ability to spell correctly is available to anyone who is willing to take a fresh look and listen to the sounds we use to speak English and the symbols we use to write the sounds.
In addition to phonics information, 7 Steps to Good Spelling contains listening exercises and a list of 150 words that SpellCheck won’t catch.
