Question: One usage—the more common among linguists—refers to a variety of a language that is a characteristic of a particular group of the language's speakers. The term is applied most often to regional speech patterns, but a dialect may also be defined by other factors, such as social class. A dialect that is associated with a particular social class can be termed a sociolect, a dialect that is associated with a particular ethnic group can be termed as ethnolect, and a regional dialect may be termed a regiolect. According to this definition, any variety of a language constitutes "a dialect", including any standard varieties.
Is there an answer to this question: What can a region that is associated with a particular ethnic group be called?

Answer: unanswerable


Question: Like in English, Dutch has generalised the dative over the accusative case for all pronouns, e.g. Du me, je, Eng me, you, vs. Germ mich/mir dich/dir. There is one exception: the standard language prescribes that in the third person plural, hen is to be used for the direct object, and hun for the indirect object. This distinction was artificially introduced in the 17th century by grammarians, and is largely ignored in spoken language and not well understood by Dutch speakers. Consequently, the third person plural forms hun and hen are interchangeable in normal usage, with hun being more common. The shared unstressed form ze is also often used as both direct and indirect objects and is a useful avoidance strategy when people are unsure which form to use.
Is there an answer to this question: What language besides Dutch uses the dative case instead of the accusative for pronouns?

Answer: English


Question: Earth's surface and the clouds absorb visible and invisible radiation from the sun and re-emit much of the energy as infrared back to atmosphere. Certain substances in the atmosphere, chiefly cloud droplets and water vapor, but also carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, and chlorofluorocarbons, absorb this infrared, and re-radiate it in all directions including back to Earth. Thus, the greenhouse effect keeps the atmosphere and surface much warmer than if the infrared absorbers were absent from the atmosphere.
Is there an answer to this question: What substances absorb the sulfur hexafluoride emitted by the Earth?
