This little book attempts to explain English spelling rules, traditions, commonalities and the many exceptions. It's sensibly organised but the alphabetical approach doesn't adapt easily to the 44 phonemes. I bought it to help me to make revision notebooks for dyslexic students. Study it before you use it for reference. (I made my own page reference.) To help dyslexic readers it needs to be a larger format and much more clearly arranged on the page.
Useful for working out your own spelling curriculum and the best (simplest and most comprehensive) I've found yet.
Trainee teachers, get it and use it.
GOOD VALUE.
