Quoits: A lawn game where you throw a ring (the "quoit") over a peg (the "hob"). Similar to horseshoes.
Spats: A sort of "shoe cover" apparently meant to keep shoes clean, but really just an ostentatious fashion accessary.
Couvert: The early French way of spelling (and I guess pronouncing) the "cover" charge that we have today. I haven't found an explanation for why the spelling changed, but the practice of a restaurant owner charging customers a flat fee for entertainment probably started in France.
Model: Today's "designer original."
Mannikin: Today's "model" (that is, a human who models clothes for a crowd).
Manufactory: Today's "factory."
Table d'hôte: A multi-course meal in a restaurant with a flat rate but very few choices.
