Because is a connecting word that introduces a reason. When you place because at the start of a clause, that clause explains why an action occurred. On its own, a reason clause is dependent and cannot stand as a complete thought. It needs a main clause that describes the outcome.
Because our flight was delayed, we stayed at the airport hotel.
