Subordination

Subordination is the insertion of a subordinate (dependent) clause into a main clause. In the following example, the subordinate clause is in bold typeface: We won the match even though Frances couldn't play.

Subordinate clauses express additional information about some element of the main clause, and can function as modifiers, adjuncts or complements.

Basic facts about subordination

Subordination involves the combination of a main clause with a subordinate clause. Subordinate clauses express additional information about some element of the main clause, and can function as modifiers, adjuncts or complements. For example, I want to go to the beach this weekend.

Subordinate clauses often (but not always) have a different structure to main clauses and may not be grammatical as independent utterances. For example, *to go to the beach this weekend is not a complete sentence.

Sentences that contain a subordinate clause are called complex sentences. The structure of a complex sentence is given in the diagram below. The subordinate clause is internal to the main clause:

Finite versus non-finite subordinate clauses

One way of distinguishing among subordinate clauses is to identify the type of verb they contain. Verbs in subordinate clauses are either finite or non-finite. Clauses with verbs of each type are associated with different kinds of subordination.

Content clauses are a type of finite subordinate clause. Their subordinate status may be marked by the subordinator that in some environments. The distribution of that in subordinate clauses can be summarised as follows:

Non-finite subordinate clauses, like to go to the beach this weekend or the bolded clause in Nadine prefers playing tennis are typically complements to the main clause. There are four kinds of non-finite clause. All of them are headed by non-finite verbs of different kinds:

Relative clauses

A relative clause is a finite clause that modifies a noun and is a constituent of the noun phrase which has the noun as its head (for example, the umbrella that I borrowed).

Relative clauses can begin with a relative pronoun (such as which, that or who), a preposition and a relative pronoun (for example, to whom, for which) or no subordinator (for example, the umbrella I borrowed).

To identify a relative clause without a subordinator, we can insert a relative pronoun to see if the sentence still makes sense, for example, the umbrella (that) I borrowed.

Restrictive versus non-restrictive relative clauses

Relative clauses can be used in two functions, either to provide additional defining information or to make parenthetical comments. These two types of relative clauses are not strongly distinguished in spoken Standard Australian English and are not always treated consistently in written Standard Australian English but the distinction can have significant consequences in terms of prosody, punctuation and syntax.

Fused relatives

In fused relative clauses there is one element that acts both as the head of the NP and as the relativised constituent in the relative clause.

The sentence The person who said that is being hysterical contains a non-fused relative clause.

It can be expressed with the fused relative Whoever said that is being hysterical. Where whoever is the head of the NP and also a part of the relative clause.

The main clause could also be expressed as:

Someone is hysterical.

while the relative clause could be restated as:

Someone said that.

Comparative clauses

Comparative clauses are finite subordinate clauses that are used to compare two different situations. One is encoded in the main clause and the other appears as the subordinate clause.

Comparative clauses typically modify an adverb or an adjective, and are introduced by as or than (for example, The cricket match was longer than we anticipated or Peter played as well as he has ever played).

Comparative clauses introduced by as can also function to modify verb phrases (for example, Rabbit is running as fast as he can).
