Voltaire's famous Essai sur les moeurs des nations is an elaborate historical disquisition in nearly two hundred chapters.
First may be mentioned Le Livre des Faits et bonnes Moeurs du sage roi Charles V.
He also wrote on grammar, but some of his best work consists of short academic essays, and of a moral study called Considerations sur les Moeurs de Notre Temps, which is both well written and shows discernment.
A third member of the same class, Saurin, already twice mentioned, must be mentioned again, and still more deservedly, for Les Moeurs du Temps.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "moeurs" in a variety of sentences. We hope that you will now be able to make sentences using this word.
