Various types of relative clauses are attested in DGS. Relative clauses are used to modify nouns, i.e. they have an adjectival attributive function. Like many languages, DGS distinguishes between restrictive and non-restrictive (appositive) relative clauses. Restrictive relative clauses are used to identify the (set of) entities(s) the head noun denotes. In DGS, restrictive relative clauses can be formed with a sentence-initial relative pronoun that agrees with the head noun in its spatial modification. In addition, DGS non-restrictive relative clauses are typically used to provide additional (background) information.
