"Rome is in Italy."
Translation:Roma est in Italia.
The correct form is "Roma" (nominative singular), but "Romae" is incorrectly marked as a typo--it's genitive singular or nominative plural.
Typically, the verb is at the end of the sentence or clause, but forms of 'to be' (sum, es, est...) can be anywhere in the sentence.
Thanks Daniel... I had no memory about this... As I said in another post, if I refer to Rosa, rosa, rosam, rosae, rosae, rosa Locative is a regular form to conjugate words... I think that the real problem isn't the few words that obey to the locative rule but the few words who don't obey to the locative rule...
