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 articles.
In all words or word-groups of four or more syllables bearing the chief accent on a long syllable, a short unaccented medial vowel was necessarily syncopated, but might be restored by analogy
In phonology, an allophone is one of multiple possible spoken sounds – or phones – used to pronounce a single phoneme in a particular language. For example, in English, the voiceless plosive and the aspirated form are allophones for the phoneme, while these two are considered to be different phonemes in some languages such as Central Thai. Similarly, in Spanish, and are allophones for the phoneme, while these two are considered to be different phonemes in English.
Grimm's law is a set of sound laws describing the Proto-Indo-European (PIE) stop consonants as they developed in Proto-Germanic in the 1st millennium BC. First discovered by Rasmus Rask but systematically put forward by Jacob Grimm, it establishes a set of regular correspondences between early Germanic stops and fricatives and stop consonants of certain other centum Indo-European languages.
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.
Voice or voicing is a term used in phonetics and phonology to characterize speech sounds. Speech sounds can be described as either voiceless or voiced.
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-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.
Proto-Celtic, or Common Celtic, is the hypothetical ancestral proto-language of all known Celtic languages, and a descendant of Proto-Indo-European. It is not attested in writing but has been partly reconstructed through the comparative method. Proto-Celtic is generally thought to have been spoken between 1300 and 800 BC, after which it began to split into different languages. Proto-Celtic is often associated with the Urnfield culture and particularly with the Hallstatt culture. Celtic languages share common features with Italic languages that are not found in other branches of Indo-European, suggesting the possibility of an earlier Italo-Celtic linguistic unity.
The Germanic spirant law, or Primärberührung, is a specific historical instance in linguistics of dissimilation that occurred as part of an exception of Grimm's law in Proto-Germanic, the ancestor of Germanic languages.
The Sikkimese language, also called Sikkimese, Bhutia, or Drenjongké, Dranjoke, Denjongka, Denzongpeke and Denzongke, belongs to the Tibeto-Burman languages. It is spoken by the Bhutia in Sikkim, India and in parts of Koshi, Nepal. It is the Official Language of Sikkim, India. The Sikkimese people refer to their own language as Drendzongké and their homeland as Drendzong. Up until 1975 Sikkimese was not a written language. After gaining Indian Statehood the language was introduced as a school subject in Sikkim and the written language was developed.
This article describes those aspects of the phonological history of the English language which concern consonants.
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 roots of the reconstructed Proto-Indo-European language (PIE) are basic parts of words that carry a lexical meaning, so-called morphemes. PIE roots usually have verbal meaning like "to eat" or "to run". Roots never occurred alone in the language. Complete inflected verbs, nouns, and adjectives were formed by adding further morphemes to a root and potentially changing the root's vowel in a process called ablaut.
Yanesha', also called Amuesha or Amoesha is a language spoken by the Amuesha people of Peru in central and eastern Pasco Region.
In phonology, voicing is a sound change where a voiceless consonant becomes voiced due to the influence of its phonological environment; shift in the opposite direction is referred to as devoicing or desonorization. Most commonly, the change is a result of sound assimilation with an adjacent sound of opposite voicing, but it can also occur word-finally or in contact with a specific vowel.
Konkani is a southern Indo-Aryan language belonging to the Indo-European family of languages spoken in the Konkan coastal region of India. It has approximately 3.6 million speakers.
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.
This article aims to describe the phonology and phonetics of central Luxembourgish, which is regarded as the emerging standard.
