Who doesn't use:
Thirty days hath September,
April, June and November,
all the rest have thirty-one...
to remind themselves which months have 30, 31 or 28 days?
This book is nothing but mnemonics like the above, for just about everything: spelling, grammar, mathematics, history, science, health and a few other odds and ends.
My mom used to teach me mnemonics as a little kid; mostly for spelling. (Geography and Mississippi.) My dad taught me one for weather. They were incredibly helpful for a kid trying to remember things that felt huge. The geography and weather mnemonics, or variations of them, made it into the book, but am I the only one who learned how to spell Mississippi by saying:
M, I, crooked-letter, crooked-letter, I, crooked-letter, crooked-letter, I, hump-back, hump-back, I?
Anyway, this was a fun, quick read for a language lover and there were quite a few useful aides here for future Trivial Pursuit challenges.
