 As a result of the untenability of the noun case system after these phonetic changes, Vulgar Latin shifted from a markedly synthetic language to a more analytic one.The genitive case died out around the 3rd century AD, according to Meyer-Lübke, and began to be replaced by + noun (which originally meant "about/concerning", weakened to "of") as early as the 2nd century BC .Exceptions of remaining genitive forms are some pronouns, many fossilized combinations like sayings, some proper names, and certain terms related to the church.
