In one of the examples Ehwald adduces, Fast II 18, uacat is found in only a few manuscripts, and it can easily be seen how it arose from uacas; all the other examples are instances of quod superest or quod reliquum est.
Ehwald favoured quod (KB 48), but all except one of the passages he cited are instances of quod superest or quod reliquum est.
His rebus confectis Caesar, ut reliquum tempus a labore intermitteretur, milites in proxima municipia deducit; ipse ad urbem proficiscitur.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "reliquum" in a variety of sentences. We hope that you will now be able to make sentences using this word.
