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. In the study of Historical linguistics and phonetic change a chain shift is a type of sound shift in which a group of sounds all change at about the same time Jacob Ludwig Carl Grimm ( Hanau, January 4, 1785 &ndash September 20, 1863 in Berlin) German Philologist Proto-Germanic, or Common Germanic, is the hypothetical common ancestor ( Proto-language) of all the Germanic languages such as modern English The 1st millennium BC encompasses the Iron Age and sees the rise of successive empires 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). The Germanic languages are a group of related languages that constitute a branch of the Indo-European (IE Language family. A stop, plosive, or occlusive is a Consonant sound produced by stopping the airflow in the Vocal tract. Fricatives are Consonants produced by forcing air through a narrow channel made by placing two articulators close together Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. Greek (el ελληνική γλώσσα or simply el ελληνικά — "Hellenic" is an Indo-European language, spoken today by 15-22 million people mainly 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[1]:
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. Proto-Germanic, or Common Germanic, is the hypothetical common ancestor ( Proto-language) of all the Germanic languages such as modern English
Grimm's law was the first non-trivial systematic sound change to be discovered in linguistics; its formulation was a turning point in the development of linguistics, enabling the introduction of a rigorous methodology to historical linguistic research. Sound change includes any processes of Language change that affect pronunciation ( phonetic change) or sound system structures ( Phonological change Linguistics is the scientific study of Language, encompassing a number of sub-fields The "law" was discovered by Friedrich von Schlegel in 1806 and Rasmus Christian Rask in 1818, and later elaborated (i.

Further changes following Grimm's Law, as well as sound changes in other Indo-European languages, can sometimes obscure its effects. The most illustrative examples are used here.

This is strikingly regular. Each phase involves one single change which applies equally to the labials (p, b, bʰ, f) and their equivalent dentals (t, d, dʰ, þ), velars (k, g, gʰ, h) and rounded velars (kʷ, gʷ, gʷʰ, hw). The first phase left the phoneme repertoire of the language without voiceless stops, the second phase filled this gap but created a new one, and so on until the chain had run its course.
The voiceless stops did not become fricatives if they were preceded by *s (itself a fricative).

| *skʷ | English: scold, Old Norse: skäld, Icelandic: skáld, Dutch: schelden | Irish: scioll |
Furthermore, the voiceless stop *t also did not become a fricative if preceded by *p, *k, or *kʷ (themselves voiceless stops). The voiceless stop it was preceded by did fricativize, however. (In other words, at the time in history when voiceless stops fricativized in Proto-Germanic, that fricativization only affected leading voiceless stops when paired with the voiceless stop *t. ) This is sometimes treated separately under the heading Germanic spirant law:

The most recalcitrant set of apparent exceptions to Grimm's Law, which defied linguists for a few decades, eventually received explanation from the Danish linguist Karl Verner (see the article on Verner's law for details). In Linguistics, the Germanic spirant law or Primärberührung is a specific historical instance of assimilation which occurred at an early stage in the Karl (Adolph Verner ˈʋaɐ̯ˀnɐ (born 7 March, 1846 in Århus; died 5 November, 1896 in Copenhagen) was a Danish Verner's law, stated by Karl Verner in 1875 describes a historical Sound change in the Proto-Germanic language whereby voiceless fricatives *
The Germanic "sound laws", combined with regular changes reconstructed for other Indo-European languages, allow one to define the expected sound correspondences between different branches of the family. For example, Germanic (word-initial) *b- corresponds regularly to Latin *f-, Greek pʰ-, Sanskrit bʰ-, Slavic, Baltic or Celtic b-, etc. Sanskrit (sa संस्कृता वाक् saṃskṛtā vāk, for short sa संस्कृतम् saṃskṛtam) is a historical The Slavic languages (also called Slavonic languages) a group of closely related Languages of the Slavic peoples and a subgroup of Indo-European languages The Baltic languages are a group of related languages belonging to the Indo-European language family and spoken mainly in areas extending east and southeast of the Baltic The Celtic languages are descended from Proto-Celtic, or "Common Celtic" a branch of the greater Indo-European Language family. , while Germanic *f- corresponds to Latin, Greek, Sanskrit, Slavic and Baltic p- and to zero (no initial consonant) in Celtic. The former set goes back to PIE *bʰ- (faithfully reflected in Sanskrit and modified in various ways elsewhere), and the latter set to PIE *p- (shifted in Germanic, lost in Celtic, but preserved in the other groups mentioned here).
