Thank you, malone. I read this headline in today's Shropshire Star:
Whole of the country should unite as one.
Or perhaps unite as two or three? And I'm not convinced that "whole" is necessary.
The country should unite.
That in itself implies the whole country, otherwise it would have said the south of the country or England and Wales should unite.
But maybe I'm being too critical and I don't blame the subeditor who wrote the headline because I know they have to fill the space available and that means padding things out sometimes.
