Grassmann's law is named after a linguist born in which year ?
Hermann Grassmann Hermann Günther Grassmann (German: "Graßmann" ; April 15, 1809 – September 26, 1877) was a German polymath, known in his day as a linguist and now also as a mathematician. He was also a physicist, neohumanist, general scholar, and publisher. His mathematical work was little noted until he was in his sixties.
Bartholomae's law Bartholomae's law (named after the German Indo-Europeanist Christian Bartholomae) is an early Indo-European (PIE) sound law affecting the Indo-Iranian family. It states that in a cluster of two or more obstruents (stops or the sibilant *"s" ), any one of which is a voiced aspirated stop anywhere in the sequence, the whole cluster becomes voiced and aspirated. Thus to the PIE root *"bʰewdʰ-" "learn, become aware of" the participle *"bʰudʰ-to-" "enlightened" loses the aspiration of the first stop (Grassmann's law) and with the application of Bartholomae's law and regular vowel changes gives Sanskrit "buddha" "enlightened".
