Grimm's law (also known as the First Germanic Sound Shift or the Rask's-Grimm's rule), named for Jacob Grimm, is a set of statements describing the inherited Proto-Indo-European (PIE) stops as they developed in Proto-Germanic (PGmc, the common ancestor of the Germanic branch of the Indo-European family) in the 1st millennium BC. It establishes a set of regular correspondences between early Germanic stops and fricatives and the stop consonants of certain other centum Indo-European languages (Grimm used mostly Latin and Greek for illustration). As it is presently formulated, Grimm's Law consists of three parts, which must be thought of as three consecutive phases in the sense of a chain shift:
The chain shift can be abstractly represented as:
Here each sound moves one position to the right to take on its new sound value.
The voiced aspirated stops may have first become voiced fricatives before hardening to the voiced unaspirated stops "b", "d", and "g" under certain conditions; however, some linguists dispute this. See Proto-Germanic phonology.
The Brothers Grimm (German: Brüder Grimm or Die Gebrüder Grimm), Jakob Grimm (January 4, 1785 – September 20, 1863) and Wilhelm Grimm (February 24, 1786 – December 16, 1859), were German academics, linguists, cultural researchers, and authors who together collected folklore. They are among the most well-known storytellers of European folk tales, and their work popularized such stories as "Cinderella", "The Frog Prince" (Der Froschkönig), "Hansel and Gretel" (Hänsel und Gretel), "Rapunzel", "Rumpelstiltskin" (Rumpelstilzchen), and "Snow White" (Schneewittchen). Their first collection of folk tales, Children's and Household Tales (Kinder- und Hausmärchen), was published in 1812.
The brothers spent their formative years first in the German town of Hanau and then in Steinau. Their father's death in 1796, about a decade into their lives, caused great poverty for the family and affected the brothers for many years. They attended the University of Marburg where historian and jurist Friedrich von Savigny spurred their interest in philology and Germanic studies—a field in which they are now considered pioneers—and at the same time developed a curiosity for folklore, which grew into a life-long dedication to collecting German folk tales.
