Our vocabulary test keeps on doing well (over 600K tests completed now). Below is a list of 20 words known in the UK but not in the US, and a list of 20 words known in the US but not in the UK. By known we mean selected by more than 85% of the participants from that country with English as their native language. As you can see, for each word there is a difference of more than 50% between both countries.
