Grammar.
2. A sentence can be written in many
ways. It can be written as a statement, question or in negative form.

Transformational grammar relates the
active sentence “John read the book” with its
corresponding passive, “The book was read by John.” The statement “George
saw Mary” is related to the corresponding questions, “Whom [or who] did George
see?” and “Who saw Mary?” Although sets such as these active and passive
sentences appear to be very different on the surface (i.e., in such things as word order), a
transformational grammar tries to show that in the “underlying structure” (i.e., in their deeper relations to one another),
the sentences are very similar. Transformational grammar assigns a “deep structure” and a “surface
structure” to show the relationship of such sentences. Thus, “I know
a man who flies planes” can be considered the surface form of a deep structure
approximately like “I know a man. The man flies airplanes.” The notion of deep
structure can be especially helpful in explaining ambiguous utterances; e.g., “Flying airplanes can be dangerous” may have
a deep structure, or meaning,
like “Airplanes can be dangerous when they fly” or “To fly air planes can be
dangerous.”
The most widely discussed theory of transformational grammar was
proposed by U.S. linguist Noam Chomsky in
1957.
