Comparative Clauses

Express similarity or difference

► What is a comparative clause? ▼ Explanation of term

A comparative

  • expresses
    • a comparison of difference based on judgment or a standard of measurement: He is faster than I am. He is faster than me.
    • a comparison of relative equality (similarity, sameness) based on judgment or a standard of measurement: He walks as fast as I do. (about the same) He the same speed as I (do).  (equal)
  • takes form as, than, , like, of, from or to— in a paired expression with an adjective phrase or adverb phrase followed by a prepositional phrase. (He walks as fast as I walk. He walks faster than I walk. He walks the fastest of us all. He walks a different route from us / than we do. His route is similar to our route.) 
    • the preposition (as, than, , like, of, from or to) serves as the "head" of the adjunct prepositional phrase. The preposition may take a noun, noun phrase or clause as its complement.   He is as tall as I am. He is taller than me.
    • reduction of the clausal complement optionally omits the verb but may keep the auxiliary.  He walks as fast as I walk. He works as fast as I do. He works as fast as I.  (Huddleston 2 §12, 13)

adjunct (Adj) — is a structure that is added to the main clause but not required for the clause to make sense, an extra structure.
