What you'll learn

By the end of this lesson, you'll be able to nest one clause inside another for precise, sophisticated sentences.

When do I use it?

An embedded clause sits INSIDE another clause, usually as a relative clause or an additional piece of information:

  • Relative: "The idea that you proposed is brilliant."
  • Interrupted flow: "The report, which I thought was ready, is still unfinished."
  • Noun clause inside a clause: "What you said about the budget worries me."
  • Reporting inside: "The manager said that the deadline, which we doubted, was fixed."

Embedding lets you pack more information into one flowing sentence instead of several short ones.

How do I form it?

Structure

noun + relative clause embedded in the main clause clause + comma + extra clause + comma + clause

  • The proposal, which I drafted yesterday, has been approved.
  • Students who study regularly usually perform better.
  • I believe that what she told us is true.
  • The plan, however reasonable it seems, is risky.

Common mistakes for Spanish speakers

Warning

Keep the main clause intact around the embedded one: do not repeat the subject ("the report, which I thought was ready, it is still unfinished" — the "it" is wrong). Also, the embedded clause needs its own verb and word order. And do not over-embed: more than two levels ("the fact that the report that he wrote that I read...") becomes unreadable — break it up.

Hint

Insert the embedded clause with commas; keep the main clause continuous without repeating the subject.
