The most basic type of sentence is the simple sentence, which contains only one clause. A simple sentence can be as short as one word:
Run!
Usually, however, the sentence has a subject as well as a predicate and both the subject and the predicate may have modifiers. All of the following are simple sentences, because each contains only one clause:
Melt!
Ice melts.
The ice melts quickly.
The ice on the river melts quickly under the warm March sun.
Lying exposed without its blanket of snow, the ice on the river melts quickly under the warm March sun.
As you can see, a simple sentence can be quite long -- it is a mistake to think that you can tell a simple sentence from a compound sentence or a complex sentence simply by its length.
