Fascinating Fact:

A main clause makes sense alone. A subordinate clause needs a main clause. Example: I stayed inside because it rained.

In 11 Plus English, you learn how clauses and phrases work together to form clear sentences. A main clause can stand alone, while a subordinate clause depends on it for full meaning.

  • Clause: A group of words with a subject and a verb.
  • Phrase: A group of words without a full subject and verb that acts as one part of speech.
  • Subordinating conjunction: A word that introduces a subordinate clause, for example because, although, when.
What is the difference between a clause and a phrase?

A clause has a subject and a verb, for example I ran. A phrase does not have both and cannot stand alone, for example in the park.

How do I identify a main clause and a subordinate clause?

A main clause can be a sentence on its own. A subordinate clause begins with a subordinating conjunction and relies on the main clause for complete sense.

What punctuation do I use with subordinate clauses?

If a subordinate clause comes first, use a comma before the main clause, for example Because it rained, we stayed inside. No comma is needed when it comes second.

The text only contains an independent clause
The text only contains a dependent clause
The text contains both a dependent clause and an independent clause
The text contains neither a dependent clause nor an independent clause
Dependent clause: 'Although he was tired' (note the use of a comma when the sentence starts with a dependent clause). Independent clause: 'he carried on swimming'
2 .
... , he was very clever.
The text contains neither a dependent clause nor an independent clause
The text only contains a dependent clause
The text contains both a dependent clause and an independent clause
The text only contains an independent clause
The comma shows that something else precedes the independent clause: it could be a dependent clause
3 .

The text contains neither a dependent clause nor an independent clause
This is a phrase

The text contains both a dependent clause and an independent clause

5 .

6 .

The text contains both a dependent clause and an independent clause
The text only contains a dependent clause
The text only contains an independent clause
The text contains neither a dependent clause nor an independent clause
Independent clause: 'He knew where the key was'. Dependent clause: 'since he had seen her hide it'. This sentence can also be written as 'Since he had seen her hide it, he knew where the key was'. (Note the use of a comma when the sentences starts with a dependent clause)
7 .
Wherever he looked,...
The text only contains an independent clause
The text contains both a dependent clause and an independent clause
The text only contains a dependent clause
The text contains neither a dependent clause nor an independent clause
The text does not express a complete thought. You should now have started to realize that dependent clauses often start with words such as 'although', 'because', 'since', 'though', 'as' and 'if'. It is these words that prevent the dependent clause from expressing a complete thought
