How can I identify the direct object and indirect object? It's difficult for me to understand them. I want to be sure that I understand them.

Answer 1

First, a Direct Object is the direct target of the verb.

Examples:

The hammer hits the nail.

Fred paints the car.

One example of an INdirect object:

Fred throws Bill the ball.

the fundamental statement is "Fred throws the ball.", by adding "Bill" more information is provided.

Here is a definition found with a Google search:

a noun phrase referring to someone or something that is affected by the action of a transitive verb (typically as a recipient), but is not the primary object (e.g. him in give him the book ).
