My brother cut the grass on Saturday.
It is a simple sentence since it contains a subject (<em>My brother</em>) and a verb (<em>cut)</em>. It also has a direct object (<em>the grass</em>) and a prepositional phrase of time (<em>on Saturday</em>). It is important to state that a sentence must have a complete idea and stands on its own. That's why this type of sentence is called independent clause.
