How would one write the expression "lowlands" in contemporary Latin? Would it be like in Spanish, terra bassa, or would it be something like terra subiecta or even terra infera?
I would prefer an answer with a source, if possible, but if you do not have one, an educated guess is more than welcome. I personally find terra infera reminds me too much of the netherworld or something of the sort, but I am not sure of the value of the other options.
