What type of sentence contains a main clause and one or more subordinate clauses?

A complex sentence contains a main clause and one or more subordinate clauses (aka dependent clauses). The main clause is an independent clause that could be its own simple sentence because it expresses a complete idea and has a subject and a verb.

For example, each of these complex sentences has a main clause in bold.

  • If they make another Spider-Man movie, we have to go see it when it’s at the cinema.
  • The meeting ended abruptly because the Wi-Fi was down.
