Relative adverb vs. non-relative adverb (CGEL)

Relative adverb

In CGEL, a relative adverb is a special type of adverb that introduces a relative clause and at the same time functions as a constituent within that clause, typically indicating time, place, or reason. Its main role is to connect the relative clause to its antecedent and specify the circumstances of the event described.

  • A subclass of adverb that heads a relative clause.

  • Has anaphoric reference to an antecedent (typically an NP).

  • Simultaneously:

    • introduces the relative clause, and

    • expresses a gap-related function within that clause (often adjunct-like).

Common relative adverbs in CGEL:

  • where (place)

  • when (time)

  • why (reason)

Example:

  • the place where we met

    • where = relative adverb

    • where we met = relative clause modifying place

    • where corresponds to a locative gap inside the clause (we met __)

Key properties:

  • Occurs only in relative clauses

  • Has an antecedent

  • Not replaceable by there / then / for that reason without restructuring


Non-relative adverb

  • An ordinary adverb (or adverbial PP) with no antecedent.

  • Does not introduce a relative clause.

  • Functions directly as adjunct, modifier, or supplement.

Examples:

  • We met there

    • there = non-relative adverb

    • No antecedent

    • No clause-introducing role

  • She left when it got dark

    • when = subordinator (not relative)

    • Introduces a temporal adjunct clause, not a relative modifier of an NP

CGEL alignment note

  • A relative adverb is not a complementizer.

  • Complementizers (that, whether, if) are heads of content clauses.

  • Relative adverbs are heads of relative clauses and encode semantic relations (place, time, reason) tied to an antecedent.
