Could I suggest a tile-select version or click quiz, not sure what the name is, I always mix those up (You get a name and then select what goes with it). It will make it easier for those that can't come up with the names, and harder for those that can but are just spamming names now.
We just want the names of the currencies, without presuming to claim what they might translate into in other languages. The suffix -avo means portion in Spanish, so in any case 'centavo' would not be a direct translation from the English word 'cent' anyway.
You are confusing meaning and etymology here. "Cent" in English means exactly the same than "Centavo" in Spanish, which is a 1/100th of any basic currency unit. Every bilingual dictionary will give them as direct translations, and a Spanish speaker will talk about "centavos" even when referring to a fraction of a dollar.
No it wouldn't. What you're saying is the equivalent of claiming John and Ivan are the same names because they are "direct translations" of each other.
come to think of it... I think I've had every one of these currencies in my pocket before, in some form or another, at one point or another, except for the Brazilian real and the South African rand. Though the pesos and centavos I had I think may have used different symbols I'm not sure.
oh wait, also never any Chinese Yuan... though I have had a wallet full of Hong Kong dollars.
14 countries, mainly in Latin America, use centavos. Centavos have 100th of the value of their larger currency units, which vary from country to country but which include reals, pesos and bolivianos,
I'd suggest replacing it for ₿ (the bitcoin sign).
But be it as you will. Your test, your rules. :)
Vowels are underrepresented it seems...
