Apparently the sentence is incorrect without the 'in' before America. I am obviously missing some gramatical point? Perhaps someone can enlighten me?
In America is in America. Only cities and a few other words omit the in and use the Locative.
Thanks, I think I'm beginning to recognise the logic from the many wrong answers I have had corrected!
Why not "quot iuvenes est in america?
Iuvenes sunt is a plural form.
Iuvenis est is a singular form.
Why is multae (many) left out.
It's not left out.
Quot - how many
Most languages have one word for the question "how many". English uses two words.
Yup, quanto, cuanto, combien, &c.
