Joining clauses with conjunctions

An illustration of a young girl smiling and working at a desk.

A conjunction is a word, or words, used to connect two clauses (parts of a sentence) together.

Some examples of conjunctions include:

  • and
  • but
  • or
  • because

Conjunctions can be used to join two sentence clauses together.

Here are two sentences:

Lilly ate an ice cream. She read a book.

Using a conjunction they can be joined to make one sentence, like this:

Lilly ate an ice cream and read a book.
