What are conjunctions?

Conjunctions are words that link clauses together (clauses = different parts of a sentence).
Some common conjunctions:

yetsincesoalthough

How to use conjunctions

Before using conjunctions, you must know that long sentences are built by putting pieces together. These pieces are clauses.
Clause 1: I like ice cream.
Clause 2: It is delicious.
Together with conjunction: I like ice cream because it is delicious.
