Although, though, even though, in spite of, and despite are words that help us connect contrasting ideas clearly and fluently. We use them to introduce a clause in a sentence which is in contrast to another clause in the same sentence.
You already know how to use basic connectors such as so and but. In the example below, but is a contrast connector.

Now, it’s time to learn other connectors that help us communicate more complex ideas.

NOTE: A dependent clause is NOT a full sentence. It is a phrase (group of words) that is incomplete, in other words, it is an incomplete thought. We need to complete the idea by using a connector and an independent clause.
An independent clause is a phrase that contains a subject and verb and expresses a complete thought.
