Listing
In listing a series of elements, the explicit links may be omitted, although the coordinator is typically retained between the last two items, as in 1. Moreover, the repetition of a coordinate adds extra emphasis to the relation expressed, as in 2:
1 We have bought bread, ham, cheese, fruit and beer for the picnic.
2 They would walk and talk and bathe and read and joke.
Meanings can be reinforced by using correlative coordinates. Else (or else) and the correlative coordinators either . . . or make explicit the meaning of alternation (either we stay or (else) we leave now), which excludes one alternative, while the negative correlates neither . . . nor exclude both (He likes neither tea nor coffee).
You should either accept his offer or (else) never see him again.
Either we give the tickets back or (else) we drop everything and go.
You should neither ask him for money nor accept it if he offers.
With an additive meaning, the correlates not only . . . .but also function in a similar way:
Mary not only runs a kindergarten but also writes books on childcare
If not only is placed in clause initial position, subject-verb inversion is obligatory, in this case involving the use of a form of do:
Not only does Mary run a kindergarten but she also writes books on childcare.1
The same applies to neither and nor in clause-initial position, following a previous negative statement.
I was not satisfied with the result and neither /nor were they.
