Updated on March 09, 2020Subordination in English grammar is the process of linking two clauses in a sentence so that one clause is dependent on (or subordinate to) another. Clauses joined by coordination are called main clauses or independent clauses. This is in contrast to subordination, in which a subordinate clause (for example, an adverb clause or an adjective clause) is attached to the main clause.
Clausal subordination is often (but not always) indicated by a subordinating conjunction in the case of adverb clauses or a relative pronoun in the case of adjective clauses.
For a clear and complete definition of subordination and how it allows readers to connect ideas, read this excerpt from Sonia Cristofaro's book, Subordination. "[T]he notion of subordination will be defined here exclusively in functional terms. Subordination will be regarded as a particular way to construe the cognitive relation between two events, such that one of them (which will be called the dependent event) lacks an autonomous profile, and is construed in the perspective of the other event (which will be called the main event).
This definition is largely based on the one provided in Langacker (1991: 435-7). For instance, in Langacker's terms, the English sentence in (1.3),
(1.3) After she drank the wine, she went to sleep.
profiles the event of going to sleep, not the event of drinking the wine. . What matters here is that the definition pertains to cognitive relations between events, not any particular clause type. This means that the notion of subordination is independent of the way in which clause linkage is realized across languages," (Cristofaro 2005).
"In the sentence, I swear that I didn't dream it, where one clause is part of the other, we have subordination," begins Kersti Börjars and Kate Burridge in Introducing English Grammar. "The higher clause, i.e., the whole sentence, is the main clause and the lower clause is a sub-clause. In this case, there is an element which actually marks explicitly the beginning of the subordinate clause, namely that," (Börjars and Burridge 2010).
Adverbial clauses are subordinate clauses that begin with subordinate conjunctions and function as adverbs. Here are some examples.
Adjectival clauses are subordinate clauses that function as adjectives. See these examples.
Donna Gorrell, author of Style and Difference, argues that the subordinate sentence type is at once prominent and difficult to correctly use. "Subordination-heavy sentences are probably our most common type of sentence, either spoken or written, though they are more complicated than they may seem at first glance. In fact, this sentence by Thomas Cahill seems quite ordinary until we examine it more closely:
In the time-honored fashion of the ancient world, he opens the book at random, intending to receive as a divine message the first sentence his eyes should fall upon. —How the Irish Saved Civilization (57).
Cahill's basic sentence about St. Augustine is 'he opened the book.' But the sentence begins with two orienting prepositional phrases ('In the time-honored fashion' and 'of the ancient world') and adds detail at the end with a prepositional phrase ('at random') and a participial phrase ('intending . . .'). There is also an infinitive phrase ('to receive . . .') and a subordinate clause ('his eyes should fall upon'). For the reader, comprehending this sentence is much simpler than describing it," (Gorrell 2004).
Subordination is commonplace in English, but this is not true of all languages. Here's what expert James Huford has to say about this. "Many languages make very sparse use of clause subordination while making much freer use of clause conjoining.
We can extrapolate that the earliest languages had only juxtaposition of clauses, then developed markers of coordination of clauses (like and), and only later, perhaps much later, developed ways of signaling that one clause was intended to be understood as playing a role inside the interpretation of another, i.e. marking subordination of clauses," (Hurford 2014).
