The primary sentence structures are the sentence structures of the verb. They represent sentences with complements that are governed by the valency of the verb. In contrast, secondary sentence structures represent sentences containing complements that are governed by an adjective.
The sentence structures are presented by means of example sentences. The example sentences are always declarative sentences in which the subject comes first. Nevertheless, the sentence structures also cover other sentence types and different word orders, i.e. they also apply to sentences in which the same complements appear in different order. See
All kinds of constituents can be complements. There are, however, some special cases causing difficulties when it comes to determining the complements in a sentence (e.g. the impersonal pronoun es, the reflexive pronouns). See List of complements and special cases.
