Is there any particular reason why "We have a second one" is not acceptable?
Does "uno secondo" work if you want to emphasize the amount? Or is that only used when you want to count from one?
You just say "un". If you don't want it confused with "a", you say "un solo" or something.
"Uno" or "Lo" is used for masculine words beginning with z or s + consonant. You say: "Uno stadio/Lo stadio" or "Uno zio/Lo zio" "Lo/Uno zucchero" "Lo sport" etc. (I have an Italian passport but I am not a grammar expert!!!) Hope that is okay.
Does second refer to the time 'one second'? Then why is it in the number section?
Is "let's have a second" valid? I thought this could be a valid usage of the second person plural as in "andiamo", let's go.
is "un" here refer to "a" or to one? If for one, why it is not uno secondo instead of un secondo?
The word "a" is missing from the choices. This problem has been happening lately in other lessons too. Of course my sentence was wrong but there was nothing I could do to fix the problem. I reported it.
