Question

Non defining relative clauses are..................................part of the sentence. For example:................................................​

Answer 1

Non-defining relative clauses are complement or part of the sentence. For instance:

In the compound sentence: "I forgot the pencil your brother gave me"

The main sentence is "I forgot the pencil"

The sentence "your brother gave me" is a non-defining relative clause

In other words, this type of clause works as an adjective to modify a noun in the main clause.
