Duplication Rule

[…] linguistic usage has developed, which can be read in formulations such as "secret code" , "Morse Code", "genetic code" or in the communication-theoretical speech of coding, decoding, recoding.

Also here one could think, and this will have motivated linguistic-historically this branching off, first of all of a coherent series of symbols – e.g. of the "Morse alphabet".

The striking thing of these codes is, however, that here a duplication rule is present, which makes it possible to give to each item of the one symbol system a correlate in another – in the case of the genetic code thus all information, which is passed on as hereditary material, to use also for the construction of a living and dying organism.

In this sense one can already call the language a code – not because it contains many combinable symbols, but because it makes it possible to communicate everything what is communicated in yes-version and in no-version, and this, although one knows that negatives, except in the communication, do not exist at all.

The language code can then be duplicated in its turn, namely by writing; and at least since the invention of phonetic scripts this is possible for every linguistic expression, thus as universal coding.
