I love crossword puzzles even though I'm terrible at them. Except for the ones in People Magazine - I kick butt at those! But when it comes to The New York Times Sunday Crossword - I call it a success if I can complete half!
Doing high-quality crossword puzzles is a fun way to learn SAT, ACT, or GRE vocabulary words.
The people who design crossword puzzles - also known as cruciverbalists - are the ultimate logophiles. They love sticking in fun and often obscure words (also known as SAT/ACT/GRE vocabulary words!) whenever and wherever they can.
More importantly, cruciverbalists also love to include lesser-known secondary definitions of commonly-used words - e.g., canvas, bear, abandon - which incidentally, is what test makers love to test on the SAT/ACT/GRE too!
