Is a company always plural, or are small companies singular?
I came across a mocked up newspaper article earlier and there was a discussion about whether the following is grammatically incorrect:
"Black Friday as Sweden destroys us"
To me, this looks wrong. I'd always say:
"Black Friday as Sweden destroy us"
To add context this comment would relate to the Swedish national football team defeating the English team. I presume therefore that Sweden is treated as a plural/collection, but I can't find a definitive answer anywhere.
