I'm posting this because it is the system I learned in the 1960s for memorizing lists of words. I lost the book in the 1970s, but still knew the system and for a party trick could memorize lists of 50 words or so. Just this week I found the name for the system - "Major System (also called the phonetic number system, phonetic mnemonic system, or Herigone's mnemonic system)" and was able to look up some information about it in Wikipedia.
The process involves substituting consonants for numbers and thereby creating words. The first 25 key words are as follows: 1 tea, 2 Noah, 3 May, 4 ray, 5 law, 6 Shaw, (author) 7 key, 8 fee, 9 bay, 10 tease, 11 tot, 12 tan, 13 team, 14 tar, 15 tale, 16 touch, 17 tack, 18 taffy, 19 tap, 20 niece, 21 net, 22 noon, 23 name, 24 Nero, 25 nail...
The full list of words and the details of the system are available at Good Memory Secrets, but I don't think that's the original source.
Posted because if I forget the words, I now can go to my blog and look them up.
