Memorization is probably the fastest way to learn very basic meanings,if you can stand it...I never could. But the best way is a much more rounded and complete learning system. So instead I'm recommending 3 books to you to look at. Each of them is probably better than your local Tarot Teacher. Each of them can --with your work--turn you into a Tarot Reader, not a Tarot Parrot.
First Louis's "Tarot Plain and Simple". It has keywords, but also a long list of possible meaning for each card and encourages you to see each card in a rounded way. It get s you started using your intuition from the beginning in a natural way, It just happens.
2nd, Greer's "21 Ways to Read a Tarot Card" Takes a bit longer, is an amazing course, worth doing over and over again at each level of reading you come to.
3rd, despite the Hokey title, Dusty White's "The Easiest Way to Learn the Tarot--EVER!!" It's a combo workbook and text, and excellent.
All 3 of these books actually teach you how to READ the cards as you learn their meanings, how to combine them, how to let you intuition in, how tho understand spreads, etc. They are each a tremendous resource,written by excellet teachers. The other thing to do is Read, Read, Read the cards, all the time about everyting and let them teach you.
FEH on Memorization! It will NEVER make you a reader!
