QUES: In the fifth century Strasbourg was occupied successively by Alemanni, Huns, and Franks. In the ninth century it was commonly known as Strazburg in the local language, as documented in 842 by the Oaths of Strasbourg. This trilingual text contains, alongside texts in Latin and Old High German (teudisca lingua), the oldest written variety of Gallo-Romance (lingua romana) clearly distinct from Latin, the ancestor of Old French. The town was also called Stratisburgum or Strateburgus in Latin, from which later came Strossburi in Alsatian and Straburg in Standard German, and then Strasbourg in French. The Oaths of Strasbourg is considered as marking the birth of the two countries of France and Germany with the division of the Carolingian Empire.

QUES: While Old Czech had a basic alphabet from which a general set of orthographical correspondences was drawn, it did not have a standard orthography. It also contained a number of sound clusters which no longer exist; allowing e (/j/) after soft consonants, which has since shifted to e (//), and allowing complex consonant clusters to be pronounced all at once rather than syllabically. A phonological phenomenon, Havlik's law (which began in Proto-Slavic and took various forms in other Slavic languages), appeared in Old Czech; counting backwards from the end of a clause, every odd-numbered yer was vocalized as a vowel, while the other yers disappeared.

What did Proto-Slavic have that no longer exists?
