correlative coordination
Definition - The use of correlative forms, i.e. pairs of words that work together to link equivalent sentence elements.

Example -
In English, the correlative forms are
(1) both … and (He was both happy and sad at the same time.)
(2) either … or (He was always either happy or sad.)
(3) neither … nor (He was neither happy nor sad.)
(4) not (only) … but (also) (When he saw her, he was not only happy but also sad.)
(5) so … as (His smell was so bad as to make us all run away.)
(6) whether … or (He couldn't decide whether to be stupid or to be smart.)
(7) such as (Such as we saw we ate.)
(8) if … then (If you can't tell that you are man, then you must be a woman.)
(9) as … so (As sad is to happy, so angry is to calm.)
(10) such that (His happiness is such that no one can be sad around him.)
(11) so … as (His behaviour was so weird as to make us all uncomfortable.)
(12) whereas … therefore (Whereas we have failed, we shall therefore try, try again.)
(13) so … that (He was so burned that he never went out with women again.)
(14) though/although … yet (Although you love me, yet I will not buy you a coffee.)


1. Don't use neither … or. Use neither … nor or either … or.

He was neither happy or sad. (bad)
He was neither happy nor sad. (good)

2. If each of the correlative conjunction's parts refers to a clause, separate them with commas.

If he goes to the store, then he will buy some milk.
Here's the key relationship: If A then B. (no clause, so no comma)

3. To make the construction less archaic, don't hesitate to remove the yet from though/although … yet..

Although you love me, I will not buy you a coffee.
