Cum + Pluperfect Subjunctive:
In Latin, after the word “cum” (meaning “when”), a special form of the verb is found, called the SUBJUNCTIVE. The pluperfect subjunctive is translated just like the normal pluperfect, i.e. using the word had.
The pluperfect subjunctive ending always has the letters –isse followed by the person endings (m, s, t, mus, tis, nt), e.g. portav – isse – t.
E.g. cum servi omnia paravissent, mercator amicos in triclinium duxit.
When all the slaves had prepared, the merchant led his friends into the dining room.
