AUJORD’HUI. Aujourd’hui. C’est un des exemples, assez rares, ou l’o antique s’est allongé en ou à l’Académie. Nous avons conservé l[e] o primitif. Ici, ce sont les Français qui chousent. On disait jor, aujord’hui, ajorner dans l’ancienne langue, comme les Acadiens le disent. Les Champenois disent aussi aujord’hui.

O God, who for our redemption gave your only-begotten Son to the death of the cross, and by his glorious resurrection delivered us from the power of our enemy: Grant us so to die daily to sin, that we may evermore live with him in the joy of his resurrection; through Jesus Christ your Son our Lord, who lives and reigns with you and the Holy Spirit, one God, now and for ever. Amen.

CATIN. Poupée. Ce mot tiré d’un vocable grec, catharas, signifiant pur d’où Catherine, est tombé en disgrâce, et ne se dit plus, en français, que pour désigner une fille de moeurs légères. Le même sort est arrivé à sophiste qui, à l’origine, signifiait un sage. Dévot, casuiste sont également en train de dégénérer.

Le sens péjoratif de catin est de date assez récente. Voltaire, Madame de Sévigné, etc. ont employé le mot en bonne part. Ronsard appelle catin, Catherine de Médicis: «Pour te louer, ma petite catin / Je voudrais bien te faire un roquentin / Une élégie, un sonnet ou une ode».

Une chanson acadienne, importée de France sans doute, commence ainsi: «Versez-moi un ver de vin, / C’est pour saluer ma catin».

Catin était un terme de caresse en vieux français.

Pour tout le centre de la France, une catin, c’est encore aujourd’hui une poupée.

Almighty and everliving God, in your tender love for the human race you sent your Son our Savior Jesus Christ to take upon him our nature, and to suffer death upon the cross, giving us the example of his great humility: Mercifully grant that we may walk in the way of his suffering, and also share in his resurrection; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.

But, by the late 14th century, standards of French in Britain were slipping – at least in some quarters. Perhaps not such a problem at home, where English had already assumed some of the roles previously performed by French. But if British merchants wanted to export wool, or import bottles of Bordeaux, knowledge of French was still a must.

It’s around this time that the “Manieres de langage” – or “Manners of Speaking” – began to appear. These model conversations, the earliest used to teach French to English speakers, were used by business teachers who taught all the necessary skills for performing basic clerical work.
