Conjunction are words that link other words, phrases, or clauses together. Conjunction assist to form complex, elegant sentences and avoid the breakdown of an idea into short multiple sentences.
Examples:
While joining phrases with conjunctions, make sure they are parallel, (share the same structure).
Examples:
Coordinating conjunctions join the words, phrases, and clauses in a sentence.
Examples:
He tried his best but all in vain.
Note: comma is used when coordinating conjunction is joining two independent clauses.
Correlative conjunctions are pairs of conjunctions that work together. Some examples are either/or, neither/nor and not only/but also.
Examples:
Subordinating conjunctions join independent and dependent clauses. A subordinating conjunction shows some kind of relationship such as a cause-and-effect relationship, a contrast, or any other type of relationship between the clauses. Common subordinating conjunctions are because , since , as , although , though , while and whereas .
Sometimes an adverb, such as until , after or before can function as a conjunction.
Examples:
Here, the adverb until functions as a coordinating conjunction to connect two ideas: I can work (the independent clause) and until my friend picks me up. (the dependent clause).
The independent clause could stand alone as a sentence; the dependent clause depends on the independent clause to make sense.
The subordinating conjunction does not always come in the middle of the sentence. It has to be part of the dependent clause. Moreover, the dependent clause can come before the independent clause.
Examples:
If the dependent clause comes first, use a comma before the independent clause.
Make sure her work is completed before she leaves. (Comma is not required when dependant clause comes later)
