According to the structure, sentences can be divided into three types
Simple
Complex -
Compound
Simple Sentence:
We know that a sentence has a subject and a predicate. But it can have different structures.
When a sentence has only one subject and one predicate, it is called a simple sentence.
Example:
- I am a student.
- I have a daily routine.
- I maintain my daily routine.
- I go to school daily.
- I sit on the first bench.
- I have a friend. His name is Sumon.
- He shares his ideas with me.
- We play together.
- At the time he comes to our home.
- We help each other. We are good friends.
In the above examples, every sentence is a simple sentence because each sentence has one subject, one finite verb, and one clause.
Note: The part of a sentence which contains a subject and a predicate is also called a clause.
Complex Sentence:
Example:
- Health is wealth which is the root of all happiness.
- Everybody knows that health is the key to success.
- A healthy man enjoys life.
- Healthy man takes exercise regularly so that he can keep feet.
- He is so careful about his health that he does not forget to exercise.
- When he gets time, he plays in the open field.
- Though he may not have enough money, he leads a happy life.
In the above examples, every sentence is a complex sentence because each sentence has a principal clause and a subordinate clause.
A complex sentence is one type of sentence that consists of one main clause and one or more subordinate clauses.
Compound Sentence:
Example:
- It is a small country but it has a huge population.
- Most people live in poverty and cannot educate their children.
- We have many students to educate but we cannot educate them.
In the first sentence of the above passage, there are two parts: (i) Bangladesh is a small country (ii) it has a huge population. These two parts are joined by conjunction but. Moreover, each part has completed its meaning. So, the first sentence is a compound sentence. Similarly, the other sentences in the passage are compound.
When a sentence has two parts joined by a conjunction, and each part makes complete sense, it is a compound sentence.
