How to express that one thing is more important in Latin? As an example, voice of the people over voice of the king can be stated in Latin as Vox populi supra vox regis. I interested in expressing things like "family is more important than work".
Here are two ways to say "X is more important than Y":
- X plus valet quam Y. (Literally: "X is stronger than Y.")
- X maioris momenti/gravitatis/ponderis est quam Y. (Literally: "X is of more weight or importance than Y.")
In both of these the words X and Y are in the nominative. For plurals you need to pluralize the verbs (valent, sunt). The verb est or sunt can be left out.
It is also possible to say "X is above Y" as you suggest. In that case Y should be in accusative. In your example the genitives "of the people" and "of the king" stay in genitive: populi, regis. It should be vox populi [est] supra vocem regis. The verb est can be left out, but it is still understood to be there.
