Messages not covered by the predetermined list could be spelled out using a substitution table for individual letters.

We took a short set of sentences as our main text, then used the same material in the form of substitution tables.

In addition, block ciphers often include smaller substitution tables called S-boxes.

H.E. Palmer defines a substitution table as "a process by which any model sentence may be multiplied indefinitely by substituting for any of its words or word-groups, including others of the same grammatical family and within certain semantic limits".

It is the theoretical basis for pattern drills and substitution tables - an essential component of the audio-lingual method - and may be considered as the necessary counterpart to the communicative principle, i.e. teaching communication through communicating (communicative language teaching; communicative competence).

Matching an arbitrary, user-defined text entry string (or regular expression) against a fixed internal list of natural language expressions, possibly using word equivalent, alternate spelling, abbreviation or part-of-speech substitution tables, and other lexical resources, to increase the recall and precision of the matching algorithm.
