There are three general categories of conjunctions that may be used to combine sentence. Those categories are coordinating, correlative, and subordinating conjunctions.
Coordinating conjunctions are the simplest and most common. And, but, for, nor, or, so, and yet are the seven coordinating conjunction; an acronym, which will help you to remember and recognize the coordinating conjunctions more easily, is FANBOYS. This type of conjunction connects words or phrases that are similar.
American English is like British English in many ways, but it is spoken in the United States.
Subordinating conjunctions, which are also easy to use, are somewhat more complex than coordinating junctions. In order to use a subordinating conjunction, you must connect two complete ideas by making one subordinate; this means that one idea must be placed lower in importance than the other. There are quite a few subordinating conjunctions, such as after, since, unless, because, etc. Subordinating conjunctions always come before subordinating ideas.
