1961 H. A. Gleason Introd. Descr. Ling. (rev. ed.) xii. 173 It is normally stated in the form of rules which may be applied to one of the pair—an input—altering it to produce the other—an output.

1966 M. Pei Gloss. Ling. Terminol. Input, in transformational grammar, the term applied to a construction that is transformed into another..which is called the output (input: ‘he goes’; output: ‘he does go’, ‘he does not go’, etc.).

1969 W. A. Cook Introd. Tagmemic Analysis ii. 42 The transformational rule is simply a rule of change. This rule has an input string, a rule of change, and an output string. With kernel sentences as input, it is possible to set up a series of optional rules that will produce the output, the derived sentences.

1971 R. Fowler in Archivum Linguisticum 2 136 These rules..are typical of the local transformations which follow base constituent-structure rules on the present grammatical model. Their inputs and outputs are concatenated sets of syntactic..features, and their effect is to replace or add one feature in one set.
