Osthoff's law is an Indo-European sound law which states that long vowels shorten when followed by a resonant (Proto-Indo-European language (PIE) *m, *n, *l, *r, *y, *w), followed in turn by another consonant (i.e. in a closed syllable environment). It is named after German Indo-Europeanist Hermann Osthoff, who first formulated it.
The law operated in most of the Proto-Indo-European daughter languages, with notable exceptions being the Indo-Iranian and Tocharian branches in which the difference between long and short PIE diphthongs was clearly preserved.

The term Osthoff's law is usually properly applied to the described phenomenon in Ancient Greek, which itself was an independent innovation from similar developments occurring in Latin and other Indo-European languages. However, the term is often used loosely as a cover term referring to all shortening of long diphthongs in closed syllables.
Osthoff's law is, in some version, valid for Greek, Latin, and Celtic but not for Indo-Iranian and Tocharian.
Osthoff's law also probably applied in Germanic, although there is very little evidence to support or refute that claim. Some examples might be:
The traditional school of Balto-Slavic linguistics posits compensatory lengthening of liquid diphthongs before laryngeals. Following this, long vowels become acuted, and the long vowels subsequently shorten again due to Osthoff's law, leaving an acuted liquid diphthong. [3] For example:
Some linguists, most notably Kortlandt and Derksen, reject the idea of compensatory lengthening before laryngeals, instead positing that the acute reflects laryngeals directly. Moreover, they reject Osthoff's law for Proto-Balto-Slavic, and reconstruct long vowels intact, but only if they are inherited from Proto-Indo-European. One particular case that may reflect an inherited long vowel is *mḗms , which is reflected in all descendants without an acute. It appears in Lithuanian as mėsà , with ⟨ė⟩ reflecting a Balto-Slavic long vowel, as opposed to ⟨ę⟩.
The Indo-European languages are a language family native to the overwhelming majority of Europe, the Iranian plateau, and the northern Indian subcontinent. Some European languages of this family—English, French, Portuguese, Russian, Dutch, and Spanish—have expanded through colonialism in the modern period and are now spoken across several continents. The Indo-European family is divided into several branches or sub-families, of which there are eight groups with languages still alive today: Albanian, Armenian, Balto-Slavic, Celtic, Germanic, Hellenic, Indo-Iranian, and Italic; another nine subdivisions are now extinct.
In linguistics, the Indo-European ablaut is a system of apophony in the Proto-Indo-European language (PIE).
The laryngeal theory is a theory in historical linguistics positing that the Proto-Indo-European language included a number of laryngeal consonants that are not reconstructable by direct application of the comparative method to the Indo-European family. The "missing" sounds remain consonants of an indeterminate place of articulation towards the back of the mouth, though further information is difficult to derive. Proponents aim to use the theory to:
Proto-Germanic is the reconstructed proto-language of the Germanic branch of the Indo-European languages.
Proto-Indo-European (PIE) is the reconstructed common ancestor of the Indo-European language family. No direct record of Proto-Indo-European exists; its proposed features have been derived by linguistic reconstruction from documented Indo-European languages.
The Balto-Slavic languages form a branch of the Indo-European family of languages, traditionally comprising the Baltic and Slavic languages. Baltic and Slavic languages share several linguistic traits not found in any other Indo-European branch, which points to a period of common development and origin.
The history of the Slavic languages stretches over 3000 years, from the point at which the ancestral Proto-Balto-Slavic language broke up into the modern-day Slavic languages which are today natively spoken in Eastern, Central and Southeastern Europe as well as parts of North Asia and Central Asia.
Proto-Indo-European verbs reflect a complex system of morphology, more complicated than the substantive, with verbs categorized according to their aspect, using multiple grammatical moods and voices, and being conjugated according to person, number and tense. In addition to finite forms thus formed, non-finite forms such as participles are also extensively used.
Proto-Balto-Slavic is a reconstructed hypothetical proto-language descending from Proto-Indo-European (PIE). From Proto-Balto-Slavic, the later Balto-Slavic languages are thought to have developed, composed of the Baltic and Slavic sub-branches, and including modern Lithuanian, Polish, Russian and Serbo-Croatian, among others.
The Proto-Greek language is the Indo-European language which was the last common ancestor of all varieties of Greek, including Mycenaean Greek, the subsequent ancient Greek dialects and, ultimately, Koine, Byzantine and Modern Greek. Proto-Greek speakers entered Greece sometime between 2200 and 1900 BC, with the diversification into a southern and a northern group beginning by approximately 1700 BC.
As the Proto-Indo-European language (PIE) broke up, its sound system diverged as well, as evidenced in various sound laws associated with the daughter Indo-European languages. Especially notable is the palatalization that produced the satem languages, along with the associated ruki sound law. Other notable changes include:
The phonology of the Proto-Indo-European language (PIE) has been reconstructed by linguists, based on the similarities and differences among current and extinct Indo-European languages. Because PIE was not written, linguists must rely on the evidence of its earliest attested descendants, such as Hittite, Sanskrit, Ancient Greek, and Latin, to reconstruct its phonology.
The Germanic parent language (GPL), also known as Pre-Germanic Indo-European (PreGmc) or Pre-Proto-Germanic (PPG), is the stage of the Germanic branch of the Indo-European language family that was spoken c. 2500 BC – c. 500 BC, after the branch had diverged from Proto-Indo-European but before it evolved into Proto-Germanic during the First Germanic Sound Shift.
Hirt's law or Hirt–Illich-Svitych's law, named after Hermann Hirt, who originally postulated it in 1895, is a Balto-Slavic sound law that triggered the retraction of the accent under certain conditions.
Proto-Indo-European accent refers to the accentual (stress) system of the Proto-Indo-European language.
Proto-Tocharian, also spelled Proto-Tokharian, is the reconstructed proto-language of the extinct Tocharian branch of the Indo-European languages.
Proto-Slavic is the unattested, reconstructed proto-language of all Slavic languages. It represents Slavic speech approximately from the 2nd millennium BC through the 6th century AD. As with most other proto-languages, no attested writings have been found; scholars have reconstructed the language by applying the comparative method to all the attested Slavic languages and by taking into account other Indo-European languages.
Proto-Slavic accent is the accentual system of Proto-Slavic and is closely related to the accentual system of some Baltic languages with which it shares many common innovations that occurred in the Proto-Balto-Slavic period. Deeper, it inherits from the Proto-Indo-European accent. In modern languages the prototypical accent is reflected in various ways, some preserving the Proto-Slavic situation to a greater degree than others.
This glossary gives a general overview of the various sound laws that have been formulated by linguists for the various Indo-European languages. A concise description is given for each rule; more details are given in their respective articles.
The Proto-Slavic language, the hypothetical ancestor of the modern-day Slavic languages, developed from the ancestral Proto-Balto-Slavic language, which is the parent language of the Balto-Slavic languages. The first 2,000 years or so consist of the pre-Slavic era, a long period during which none of the later dialectal differences between Slavic languages had yet emerged. The last stage in which the language remained without internal differences that later characterize different Slavic languages can be dated around AD 500 and is sometimes termed Proto-Slavic proper or Early Common Slavic. Following this is the Common Slavic period, during which the first dialectal differences appeared but the entire Slavic-speaking area continued to function as a single language, with sound changes tending to spread throughout the entire area. By around 1000, the area had broken up into separate East Slavic, West Slavic and South Slavic languages, and in the following centuries it broke up further into the various modern Slavic languages of which the following are extant: Belarusian, Russian, Rusyn and Ukrainian in the East; Czech, Slovak, Polish, Kashubian and the Sorbian languages in the West, and Bulgarian, Macedonian, Serbo-Croatian and Slovenian in the South.
