Input: Read this: The migration-period peoples who later coalesced into a "German" ethnicity were the Germanic tribes of the Saxons, Franci, Thuringii, Alamanni and Bavarii. These five tribes, sometimes with inclusion of the Frisians, are considered as the major groups to take part in the formation of the Germans. The varieties of the German language are still divided up into these groups. Linguists distinguish low Saxon, Franconian, Bavarian, Thuringian and Alemannic varieties in modern German. By the 9th century, the large tribes which lived on the territory of modern Germany had been united under the rule of the Frankish king Charlemagne, known in German as Karl der Groe. Much of what is now Eastern Germany became Slavonic-speaking (Sorbs and Veleti), after these areas were vacated by Germanic tribes (Vandals, Lombards, Burgundians and Suebi amongst others) which had migrated into the former areas of the Roman Empire.

Input: Read this: Many of the coinages that have been considered (often by Aavik himself) as words concocted ex nihilo could well have been influenced by foreign lexical items, for example words from Russian, German, French, Finnish, English and Swedish. Aavik had a broad classical education and knew Ancient Greek, Latin and French. Consider roim 'crime' versus English crime or taunima 'to condemn, disapprove' versus Finnish tuomita 'to condemn, to judge' (these Aavikisms appear in Aavik's 1921 dictionary). These words might be better regarded as a peculiar manifestation of morpho-phonemic adaptation of a foreign lexical item.
Question: What is another term for words created by Aavik?

Output: Aavikisms

Input: Read this: In 1846, the United States went to war against Mexico and sent a naval and land expedition to conquer Alta California. At first they had an easy time of it capturing the major ports including San Diego, but the Californios in southern Alta California struck back. Following the successful revolt in Los Angeles, the American garrison at San Diego was driven out without firing a shot in early October 1846. Mexican partisans held San Diego for three weeks until October 24, 1846, when the Americans recaptured it. For the next several months the Americans were blockaded inside the pueblo. Skirmishes occurred daily and snipers shot into the town every night. The Californios drove cattle away from the pueblo hoping to starve the Americans and their Californio supporters out. On December 1 the Americans garrison learned that the dragoons of General Stephen W. Kearney were at Warner's Ranch. Commodore Robert F. Stockton sent a mounted force of fifty under Captain Archibald Gillespie to march north to meet him. Their joint command of 150 men, returning to San Diego, encountered about 93 Californios under Andres Pico. In the ensuing Battle of San Pasqual, fought in the San Pasqual Valley which is now part of the city of San Diego, the Americans suffered their worst losses in the campaign. Subsequently a column led by Lieutenant Gray arrived from San Diego, rescuing Kearny's battered and blockaded command.

Input: Read this: As the school suffered reduced income while still under construction, the completion and further development of the school has since depended to some extent on wealthy benefactors. Building resumed when Roger Lupton was Provost, around 1517. His name is borne by the big gate-house in the west range of the cloisters, fronting School Yard, perhaps the most famous image of the school. This range includes the important interiors of the Parlour, Election Hall, and Election Chamber, where most of the 18th century "leaving portraits" are kept.
