Learning the various terms used to define and classify clauses can be a vocabulary lesson in itself. This digital handout categorizes clauses into independent and dependent clauses. This simply means that some clauses can stand by themselves, as separate sentences, and some can't. Another term for dependent clause is subordinate clause: this means that the clause is subordinate to another element (the independent clause) and depends on that other element for its meaning. The subordinate clause is created by a subordinating conjunction or dependent word.
