Re: Do you agree with this list?
If you try to include simple spelling differences, the list would much, much longer. Many words with OU just have O in the American spelling, there are some double-consonant differences, and some Z and S differences.
For the vocabulary differences, as an American, I use the blue version except as noted below.
5- anywhere _____________anyplace - equally likely
6- luggage _____________baggage - more likely to use "luggage"
8- friend_____________buddy - unlikely to use "buddy"
9- wallet_____________billfold - I never "billfold"
10- taxi_____________cab - equally likely
18- autumn_____________fall - both
21- prison_____________jail - these are different things
27- film _____________movie - both
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
