QuestionA question is an utterance which serves as a request for information. Questions are sometimes distinguished from interrogatives, which are the grammatical forms typically used to express them. Rhetorical questions, for instance, are interrogative in form but may not be considered bona fide questions, as they are not expected to be answered. Questions come in a number of varieties. Polar questions are those such as the English example "Is this a polar question?", which can be answered with "yes" or "no".

Cotter (farmer)Cotter, cottier, cottar, Kosatter or Kötter is the German or Scots term for a peasant farmer (formerly in the Scottish Highlands for example). Cotters occupied cottages and cultivated small land lots. The word cotter is often employed to translate the cotarius recorded in the Domesday Book, a social class whose exact status has been the subject of some discussion among historians, and is still a matter of doubt. According to Domesday, the cotarii were comparatively few, numbering fewer than seven thousand people.
PeasantA peasant is a pre-industrial agricultural laborer or a farmer with limited land-ownership, especially one living in the Middle Ages under feudalism and paying rent, tax, fees, or services to a landlord. In Europe, three classes of peasants existed: non-free slaves, semi-free serfs, and free tenants. Peasants might hold title to land outright (fee simple), or by any of several forms of land tenure, among them socage, quit-rent, leasehold, and copyhold. In some contexts, "peasant" has a pejorative meaning, even when referring to farm laborers.
