Which term is defined as 'An abstract underlying structure from which the actual form of a sentence is derived'?

• A. Surface Structure
• B. Deep Structure
• C. Phonological Rules
• D. Semantic Rules

Answer: (A)

Deep structure is the abstract underlying representation of a sentence that encodes its core syntactic relations and meaning, from which the actual sentence form is derived through transformations. This explains why the deep structure determines how meanings are connected, while surface structure is simply the outward word order you hear or read after applying those transformations. Phonological rules govern pronunciation, and semantic rules govern meaning, but neither captures the underlying abstract form—that's deep structure.
