What type of sentence is the following The witness claimed she saw defendant and heard him talk about his family in terms that proud fathers often use to discuss their children?

Here's why:

* Independent Clause: "The witness claimed she saw the defendant and heard him talk about his family"

* Dependent Clause: "in terms that proud fathers often use to discuss their children"

The dependent clause modifies the verb "claimed" in the independent clause, providing further information about the nature of the witness's claim. This is what makes it a complex sentence.
