Johannes Trithemius described an interesting encoding method in his book Polygraphiae in 1508. Trithemius´ method uses a code table to assign multiple words to each letter:
a = pasa | mastra | ....
b = pase | mastre | ...
c = pasi | mastri | ...
...

The method is interesting since similar words would encode different letters whereas non similar words would stand for the same letter.
a = pasa | mastra | ....
b = pase | mastre | ...
c = pasi | mastri | ...
