What do you do when you have committed a sacrilege, when the Emperor has overheard your snide remark, when you handed in your essay late, or you forgot to attend a meeting with your superior? You may have offended a higher power, who would rightly chastise you for your misdeeds. You must now avail yourself of this person’s mercy and hope to quickly mend the breach in your friendship.
If that is the case, you’ll want to apologise for your mistake. But what better language to ask for mercy in than Latin?
