cipher does not—cipher will split the t from the h in the, for example.
For 450 years, from about 1400 to about 1850, a system that was half a code and half a cipher
dominated cryptography. It usually had a separate cipher alphabet with homophones and a codelike list of
names, words, and syllables. This list, originally just of names, gave the system its name: nomenclator.
Even though late in its life some nomenclators grew larger than some modern codes, such systems are still
called "nomenclators" if they fall within this historical period. An odd characteristic is that nomenclators
were always written on large folded sheets of paper, whereas modern codes are almost invariably in book
or booklet form. The commercial code is a code used in business primarily to save on cable tolls; though
some are compiled for private firms, many others are sold to the public and therefore provide no real
secrecy.
