The element in the main clause that the relative pronoun in the relative clause stands for (
house in the above example) is the
antecedent of that pronoun. In most cases, the antecedent is a nominal (noun or noun phrase), though the pronoun can also refer to a whole
proposition, as in "The train was late, which annoyed me greatly", where the antecedent of the relative pronoun
which is the clause "The train was late" (the thing that annoyed me was the fact that the train was being late). In a
free relative clause, a relative pronoun has no antecedent: the relative clause itself plays the role of the co-referring element in the main clause. For example, in "I like what you did",
what is a relative pronoun, but without an antecedent. The clause
what you did itself plays the role of a nominal (the object of
like) in the main clause. A relative pronoun used this way is sometimes called a
fused relative pronoun, since the antecedent appears fused into the pronoun (
what in this example can be regarded as a fusion of
that which). ==Absence==
