2. Correlative conjunctions
Correlative conjunctions are used in pairs, in order to show the relationship between the ideas expressed in different parts of a sentence. For instance, in the following example, the expression either ... or is used to indicate that the ideas expressed in the two clauses represent two alternative choices of action.
e.g. Either you should study harder, or you should take a different course.
The most commonly used correlative conjunctions are both ... and, either ... or and neither ... nor. In the table below, each pair of correlative conjunctions is accompanied by an example of its use.
Note that in the construction if ... then, the word then can usually be omitted.
if ... then If that is true, then what happened is not surprising.
both ... and He is both intelligent and good-natured.
either ... or I will either go for a walk or read a book.
