Old Saxon
The grammar of Old Saxon is highly inflected, similar to that of Old English or Latin. As an ancient Germanic language, the morphological system of Old Saxon is similar to that of the hypothetical Proto-Germanic reconstruction, retaining many of the inflections thought to have been common in Proto-Indo-European and also including characteristically Germanic constructions such as the umlaut. Among living languages, Old Saxon morphology most closely resembles that of modern High German.
