Morse Code

[igenlode]

A nifty telegraph-era dodge for learning the letters of Morse Code:

Each sign is represented by a word or combination, which can readily be associated with the letter required. In these key-words dots are represented by vowels and the isolated letters s, z, and h ; dashes by the consonants (including w and y). Thus A (dot, dash) is 'an' ; B (dash, dot, dot, dot) is 'base' ; C is 'cave' ; die, e, safe, gnu, hush, is, kit, aloe, Mr., no, PQR, Epps, QRST, are, sss, t, usk, azov, awl, yell, bruz. Of the remaining letters J is the exact opposite of B and X of P.

(Though quite how one is supposed to associate the letter O with the mnemonic "PQR" I'm not clear -- I suppose it is the letter immediately preceding that sequence... Otherwise you simply have to remember what an usk and a bruz are :p)
