Problem: The word phonology comes from the Greek , phone, "voice, sound," and the suffix -logy (which is from Greek , logos, "word, speech, subject of discussion"). Definitions of the term vary. Nikolai Trubetzkoy in Grundzuge der Phonologie (1939) defines phonology as "the study of sound pertaining to the system of language," as opposed to phonetics, which is "the study of sound pertaining to the act of speech" (the distinction between language and speech being basically Saussure's distinction between langue and parole). More recently, Lass (1998) writes that phonology refers broadly to the subdiscipline of linguistics concerned with the sounds of language, while in more narrow terms, "phonology proper is concerned with the function, behavior and organization of sounds as linguistic items." According to Clark et al. (2007), it means the systematic use of sound to encode meaning in any spoken human language, or the field of linguistics studying this use.
What language does speech as a word come from?

Namibia is the driest country in sub-Saharan Africa and depends largely on groundwater. With an average rainfall of about 350 mm per annum, the highest rainfall occurs in the Caprivi in the northeast (about 600 mm per annum) and decreases in a westerly and southwesterly direction to as little as 50 mm and less per annum at the coast. The only perennial rivers are found on the national borders with South Africa, Angola, Zambia, and the short border with Botswana in the Caprivi. In the interior of the country surface water is available only in the summer months when rivers are in flood after exceptional rainfalls. Otherwise, surface water is restricted to a few large storage dams retaining and damming up these seasonal floods and their runoff. Thus, where people don't live near perennial rivers or make use of the storage dams, they are dependent on groundwater. The advantage of using groundwater sources is that even isolated communities and those economic activities located far from good surface water sources such as mining, agriculture, and tourism can be supplied from groundwater over nearly 80% of the country.
What is the average rainfall in Namibia?
A: 350 mm per annum

By 1620, the fishermen of England's West Country controlled most of Newfoundland's east coast. In 1627, William Payne, called St. John's "the principal prime and chief lot in all the whole country". The population grew slowly in the 17th century and St. John's was the largest settlement in Newfoundland when English naval officers began to take censuses around 1675. The population would grow in the summers with the arrival of migratory fishermen. In 1680, fishing ships (mostly from South Devon) set up fishing rooms at St. John's, bringing hundreds of Irish men into the port to operate inshore fishing boats.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who controlled the east coast of Newfoundland in the 16th century?
Ah, so..
unanswerable
