material about conjunction, then please give me two sentences with different conjunction?

A conjunction is a word which connects two words or clauses or sentences and shows the relation between them. They are used to avoid making the text seem like bullet points and to make the text flow. E.g. -

Jai saw a dog on the road. He decided to adopt the dog. Jai brought the dog home.

Jai saw a dog on the road and decided to adopt the dog, so he brought the dog home.

Here ‘and’ and ‘so’ are conjunctions which are used to join the sentences and show the relation between them.
