Answer: Hi there! I'd say that the term that best fits this definition is a coordinating conjunction.
Explanation: (I hope that you don't mind me citing from a previous answer of mine to explain this.) Coordinating conjunctions are commonly called FANBOYS. It is an acronym that represents the following words:
<em>F</em><em>or</em>
<em>A</em><em>nd</em>
<em>N</em><em>or</em>
<em>B</em><em>ut</em>
<em>O</em><em>r</em>
<em>Y</em><em>et</em>
<em>S</em><em>o</em>
All the terms listed above can be used to connect independent sentence clauses, like this:
I want toast, eggs, and orange juice.
They wanted to come to the party, but their mom said no.
Jax is not helping us, so we'll have to do all the work ourselves!
