When a number of words (parts of speech) are put together in such a way that they express a complete thought, then they form a sentence.
A sentence is a group of words expressing a complete thought.
Often those who are beginning to learn a language may find it difficult to understand what is meant by a complete thought. Some students punctuate parts of sentences as if they were sentences because they do not realize that some essential element is missing. The following groups of words are not sentences since they do not express a complete thought.
The workers of the company. (This is not a complete thought since it does not specify what the workers did)
Enjoyed the party. (This is not a complete thought since it does not specify who enjoyed the party.)
The above examples are called sentence fragments.
In order to express a complete thought, a sentence must have both a subject and a predicate.
A sentence consists of two parts: the subject and the predicate.
The subject is what (or whom) the sentence is about.
The predicate is the part which says something about the subject.
My friend lives in Japan. (My friend is the subject and lives in Japan is the predicate)
Both girls are experienced swimmers. (Both girls is the subject and are experienced swimmers is the predicate)
In some sentences the subject or the predicate is only a single word, for example
But more often, the subject consists of two or more words. The entire subject, regardless of the number of words, is called the complete subject. The entire predicate is called the complete predicate.
This video explains how to recognize the complete subject and complete predicate in a sentence.
The excited crowd rushed into the building. (The excited crowd is the complete subject; rushed into the building is the complete predicate)
Is your bus usually late? (your bus is the complete subject; is usually late is the complete predicate)
The simple subject is the main word or group of words in the complete subject. The simple subject does not include the modifiers
The excited crowd rushed into the building. (The complete subject is The excited crowd. The simple subject is crowd)
Is your bus usually late? (The complete subject is your bus. The simple subject is bus)
The simple predicate, or verb, is the main word or group of words within the complete predicate.
The simple predicate may consist of a single verb or a main verb with the helping verbs.
The cat was sleeping in the basket. (The complete predicate is was sleeping in the basket. The simple predicate is was sleeping.}
They had diligently painted the boat. (The complete predicate is had diligently painted the boat. The simple predicate is had painted.)
A sentence may have two or more simple subjects and two or more simple predicates.
A compound subject consists of tow or more simple subjects joined by a connecting word.
Henry and Freddy joined a football team , (The two simple subjects are Henry and Freddy. The connecting word is and)
A compound predicate is a predicate with two or more verbs joined by a connecting word.
He bought the book and read it , (The two predicate verbs are bought and read. The connecting word is and.)
Some sentences have a compound subject and a compound predicate.
