Examples of complex sentences with subordinating conjunctions

A complex sentence consists of one or more clauses which could be a combination of two or more main clauses, or a combination of main and subordinate clauses.

A main clause is a clause that makes sense on its own and can also exist in a sentence on its own.

A Subordinate clause is a clause that does not make sense on its own and cannot be a sentence on its own. The subordinate clause explains or completes the meaning in the main class.

Two main clauses are joined by and, but or or.

Peter came to the party and the celebration started.

When a sentence consists of a main clause and a subordinate clause they are joined by a subordinating conjunction, also known as a subordinator such as when, because, although, if, etc.

Example: The subordinate clause has been highlighted

1. Internet shopping is very popular today because it is convenient.
2. Because he was burnt by the kettle, he went to the clinic.
3. Peter, who was playing in the jumping castle, was excited.

Subordinate clauses can appear in different parts of the sentence

Even with a back injury, Sam danced gracefully.

Punctuation: When subordinate clauses begin sentences, they are often separated by commas.

1. If you’re ever in France, let’s visit Paris.
2. Although she prepared her speech many times, Susan failed in the examination.
3. While waiting for the school bus, Tim at his breakfast.
