"18 English words that mean very different things in Britain and America"
http://indy100.independent.co.uk/article...hings-in-britain-and-america--b1tcKsqybb
Obviously Canada doesn't exist as an object of interest in the UK, and obviously Americans have no interest in multinational differences in English speech, so it's always up to the British to do these kinds of lists, and they only ever focus on the US. But as a Canadian, I think the discrepancies in Canada are fascinating.
1. A jumper
UK: A woollen pullover worn in the winter
US: Someone who commits suicide by leaping from a building or bridge
Canada: Do many Canadians know that a jumper is a sweater in the UK? Probably not, but is it only in Canada that a jumper is a sort of woman's dress (I think without sleeves), and not in the US? If someone said "there's a jumper there" while walking down the street, would you think of someone about to commit suicide, or a woman's dress? Me, I'd think "woman's dress."
2. A rubber
UK: An eraser for a pencil
US: A condom
Canada: In my lifetime this has changed from eraser to condom due to the influence of American movies, so it's now firmly the US meaning.
3. Nappy
UK: Something a baby wears (noun)
US: Frizzy or hairy (adjective)
Canada: If Canadians are aware of the term, it's the American meaning of frizzy African hair.
4. The first floor
UK: The floor above the ground floor
US: The ground floor of a building
Canada: US meaning.
5. Blinkers
UK: Flaps attached to a race horse's face to restrict its vision
US: Indicators on a car
Canada: Whoa, this is fascinating. "You've got blinkers on" means you're narrow-minded, but I'm not so sure Canadians are aware of the provenance of the term. But Canadians would also understand it if you mentioned the blinkers on a car.
6. A casket
UK: Another word for jewellery box
US: Another word for coffin
Canada: US meaning.
7. Fancy dress
UK: Informal party wear, dressing up as a well-known character
US: Formal party wear, including ball gowns and black tie
Canada: US meaning.
8. A flapjack
UK: A flat oatmeal snack
US: A type of pancake
Canada: Never the UK meaning, but I'm not sure the US meaning is much understood or used here.
9. A geezer
UK: A gang member, tough guy
US: An old man
Canada: US meaning.
10. Homely
UK: Used to describe a comfortable, cosy house
US: Used to describe someone who is plain or ugly
Canada: US meaning.
11. A hoo-ha
UK: An argument or disagreement
US: Female genitalia
Canada: Weird US slang, I think. But never the UK meaning.
12. A moot point
UK: Something that is up for debate
US: Something that is irrelevant
Canada: US meaning.
13. Nervy
UK: Nervous or prone to fidget
US: Bold or confident
Canada: US meaning.
14. Peckish
UK: Slightly hungry
US: Irritable or angry
Canada: UK meaning. I've never heard the US meaning before.
15. A run-in
UK: The end of a race
US: An argument or dispute
Canada: Both the UK and the US meanings, understood in context. Somehow I suspect this must be the same in the US, too.
16. Shattered
UK: Exhausted
US: Emotionally devastated
Canada: US meaning.
17. Solicitor
UK: A legal representative
US: A door-to-door salesman
Canada: I've never heard the US meaning used before. In my lifetime this has gone from the UK meaning to essentially no longer being used before, as lawyers now do the work of both barristers and solicitors. But back in the day, lawyer's offices used to have one or both of these words on their signs. Not really anymore, though.
18. Through
(As in, "The shop is open through lunch")
UK: During (lunch hours)
US: Up until (lunch hours)
Canada: I think I've seen a US-style meaning here, like "we're open through December 5" or something like that, but the UK meaning seems to make more sense to me, i.e. if someone said "we're open through lunch" I would understand that to mean that they weren't closed at lunch-time. So both the US and the UK meanings, depending on the context.
