I have no idea who Liz Claiborne is. I did have a little trouble with Liz Taylor, but honestly, I automatically thought of her as Liz, but then thought, oh, they'd be going by Elizabeth... but then looked at that other part of the clue and got it.
as a non native, it was hard to understand what you meant with 'ender'. It seemed to me as 'gerund/superlative of "Ender"' which makes little sense. Maybe rephrase as 'ending of a superlative'?
I had the same problem as effeietsanders. Only by getting one of the answers *despite* the clue, I understood what "ender" is supposed to mean. "Suffix" would indeed make the hint more clear.
Perhaps I'm being too literal, but "casa" is house. "Hogar" is home. I was wracking my brains out trying to think of a city that started with Hogar or Ogar (since the H is silent).
Because the damn Aussies insist on pronouncing things funny, there are problems with both of your Australian city clues. Melbourne is pronounced "mel-burn" like the injury from fire, not like Jason's last name. And the second vowel in Brisbane is a schwa (ə), not a long a. FYI.
Fun quiz. Got 'em all, but Calgary and Havana I only got from half the clue ('Gary' and 'Ha'). I think you've got one too many syllables there in Tokyo, but maybe that's me being pedantic.
I did this quiz for the second time exactly 5 years after the first try and I got 5 more answers. With this pace maybe in further 5 years I'll actually get to 100%.
Take away from this quiz: Now you've learned something. Liz is short for Elizabeth.
