Hello all, this is probably an incredibly easy question, but it's been nagging me and I'd like to be certain of the answer.
If the English is "The walls are ten feet high," is the Latin simply "Moenia decem pedes sunt alta?" (Mind you, the "alta" in that sentence in simply an appositive adjective in the nominative modifying "moenia.")
I'm slightly confused by the translation of "high." In the above sentence, is "alta" better represented in the ablative? That is, translating "high" as "in height" or "by height."
Also, what about taking the construction to the next step, i.e., "The walls are ten feet high and three feet thick?" Would that be "Moenia decem pedes sunt alta ac tres pedes lata?" (Again, my intent is to represent "alta" and "lata" here as nominatives.)
Anyway, I just want to be certain of my construction...
