appositive phrase.

An appositive phrase is a noun or a noun phrase that provides another name for a previously mentioned noun. The additional name given to that noun provides a clearer meaning or more information that enhances our understanding of the sentence. The phrase,<em> "an electrical engineer"</em>, provides more information about the<em> </em>noun <em>"father",</em> thus helping us to understand why the student's father was qualified to answer the question in the science textbook.
