I'd like to know what pronouns I can use inside the construction "both ... and ..." when it's used as a subject.
For this purpose, I have the following example:
the textbook "the Cambridge Grammar of the English Language", page 1494, example 39i:
(1) Both the local authority and myself have gone to the minister.
my variants:
(2) Both the local authority and me have gone to the minister. — Is it correct?
(3) Both the local authority and I have gone to the minister. — I know it's correct
So, is (2) correct?
Is there any difference between (1), (2) and (3)?
Does something change in reversing the order?
my variants:
(4) Both myself and the local authority have gone to the minister. — Is it correct?
(5) Both me and the local authority have gone to the minister. — Is it correct?
(6) Both I and the local authority have gone to the minister. — I know it's correct
So, are (4) and (5) correct?
Is there any difference between (4), (5) and (6)?
