Transformational grammar

Transformational grammar is a broad term describing grammars (almost exclusively those of natural languages) that have been developed in a Chomskyan tradition. The term is usually synonymous with the slightly more specific transformational-generative grammar (TGG).

"Grammaticalness"

Chomsky argued that the notions "grammatical" and "ungrammatical" could be defined in a meaningful and useful way. In contrast an extreme behaviorist linguist would argue that language can only be studied through recordings or transcriptions of actual speech, the role of the linguist being to look for patterns in such observed speech, but not to hypothesize about why such patterns might occur, nor to label particular utterances as either "grammatical" or "ungrammatical". Although few linguists in the 1950s actually took such an extreme position, Chomsky was at an opposite extreme, defining grammmaticality in an unusually (for the time) mentalistic way. He argued that the intuition of a native speaker is enough to define the grammaticalness of a sentence; that is, if a particular string of English words elicits a double take, or feeling of wrongness in a native English speaker, it can be said that the string of words is ungrammatical. This (according to Chomsky) is entirely distinct from the question of whether a sentence is meaningful, or can be understood. It is possible for a sentence to be both grammatical and meaningless, as in Chomsky's famous example "colourless green ideas sleep furiously". But such sentences manifest a linguistic problem distinct from that posed by meaningful but ungrammatical (non)-sentences such as "man the bit sandwich the", the meaning of which is fairly clear, but which no native speaker would accept as being well formed.

The use of such intuitive judgments freed syntacticians from studying language through a corpus of observed speech, since they were now able to study the grammatical properties of contrived sentences. Without this change in philosophy, the construction of generative grammars would have been almost impossible, since it is often the relatively obscure and rarely-used features of a language which give linguists clues about its structure, and it is very difficult to find good examples of such features in everyday speech.
