The most common types of conjunctions are the coordinating conjunctions such as "and," "or," "so" and "but." Correlative conjunctions come in pairs and include "either...or," "both...and," "not only...but also" and "neither...nor." Conjunctive adverbs such as "therefore," "consequently," "moreover" and "however" and subordinating conjunctions such as "after," "though," "whenever" and "unless" join clauses.
Coordinating conjunctions join equal items. In addition to the coordinating conjunctions listed above, the others are "nor," "for" and "yet" and are easy to remember by the acronym FANBOYS. Coordinating conjunctions join nouns, verbs, adjectives and adverbs as well as phrases and clauses. These conjunctions join independent clauses to form compound sentences.
A correlative conjunction is usually a coordinating conjunction paired with other words to connect various sentence elements. They join nouns, adjectives, prepositional phrases and independent clauses.
Conjunctive adverbs join independent clauses together to form compound sentences. In such a sentence, a semicolon follows the first independent clause, the conjunctive adverb comes after the semi-colon and a comma then precedes the second independent clause. Many conjunctive adverbs exist in addition to the ones listed above. A few others are "besides," "finally," "instead" and "meanwhile."
Subordinating conjunctions join two clauses together, in the process making one clause dependent on, or subordinate to, the other. These conjunctions appear in complex sentences. The English language also contains many other subordinating conjunctions than the ones already mentioned. Additional ones include "before," "although," "because" and "until."
