Topic: Clause

These resources relate to clauses. Understanding how clauses work is useful for appreciating the different kinds of effects that writers achieve by using different structures, and also for developing writing skills.

Clauses

Clauses are considered to be very important units in the study of language. But what is a clause? What makes it different from a word, a phrase, or a sentence? Why are clauses so important?

A clause is a powerful structure because it can express a whole situation. Here’s an example:

»

Clauses: Finite and nonfinite clauses

Look at each of these examples. Do they have present tense or past tense? Can we change the tense?

  • She feels sick.
  • I was watching TV.

In the first example, we have the present tense verb form feels. We could change to past tense: She felt sick.

In the second example, the verb phrase was watching contains the past tense form was. We could change to the present tense: I am watching TV.

Clauses: Main and subordinate clauses

Typically, a clause expresses a particular situation – an event or state of affairs. To do this, it usually needs to contain a verb. Here is an example of a clause:

This expresses an event, with the verb phoned indicating the type of event.

Here are some more examples of clauses, with the verb phrases highlighted:

Conjunctions

Conjunctions are words that link linguistic units such as words, phrases or clauses.

We distinguish coordinating conjunctions such as and, or and but from subordinating conjunctions such as because, since, when, while, etc.

Examples of coordinating conjunctions are:

Sentence types: simple, compound, complex

This unit further explains simple sentences, compound sentences and complex sentences, which were introduced in the unit 'Clauses: main and subordinate'. Simple sentences contain one clause, while compound and complex sentences contain more than one clause.

National Curriculum note: The National Curriculum now refers to sentences that contain one clause as single-clause sentences, and those that contain more than one clause as multi-clause sentences.

Tag questions

Questions like ...isn’t it?, ...haven’t they? and ...wouldn’t you? that sit on the end of a statement are called tag questions in linguistics. There’s a range of different tag questions most people call on, varying by verb, tense, person and whether the tag is positive or negative.
