Some points should be remembered to write a paragraph:-

1. We must use the title for the paragraph. First letter of each should be capital. We can write the whole title in capital letters as well.

Eg. Environmental Pollution or ENVIRONMENTAL POLLUTION

2.  We should use short and simple sentences to avoid the grammatical mistakes.

3. A paragraph must have a logical development of thoughts and it should have an introduction, a body(main points) and a conclusion.

4. We can use the linkers to join the sentences.

5. When we'll end our writing, that must be concise. That means the reader must get a complete idea. He must not think that if there is something more, that will be great.

Sample Paragraph:-

                   OUR NATIONAL FLAG 

We have a national flag which shows the independence of the nation or country. Our National Flag is a beautifully designed tricolour flag, also known as "Tiranga". Our National Flag is a symbol of unity and freedom. It was first time adopted on July 22 in 1947. It it rectangular in shape. It has three-coloured horizontal stripes. The topmost colour is saffron which symbolises sacrifice and selflessness, middle is white that is the colour of truth and purity and the lower is deep green that symbolises youthfulness and energy. It has a blue wheel at the centre that stands for activity and progress. The National Flag is very sacred to us. We love and respect our National Flag.
