A Proto-Indo-European (PIE) root word may be:
Indo-European is a major language family of Europe, the Middle East and South Asia.
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 systematically put forward by Jacob Grimm but previously remarked upon by Rasmus Rask, it establishes a set of regular correspondences between early Germanic stops, fricatives, and the stop consonants of certain other centum Indo-European languages.
Verner's law describes a historical sound change in the Proto-Germanic language whereby consonants that would usually have been the voiceless fricatives *f, *þ, *s, *h, *hʷ, following an unstressed syllable, became the voiced fricatives *β, *ð, *z, *ɣ, *ɣʷ. The law was formulated by Karl Verner, and first published in 1877.
In linguistics and etymology, suppletion is traditionally understood as the use of one word as the inflected form of another word when the two words are not cognate. For those learning a language, suppletive forms will be seen as "irregular" or even "highly irregular".
In linguistics, the Indo-European ablaut is a system of apophony in the Proto-Indo-European language (PIE).
In Irish mythology, Neman or Nemain is the spirit-woman or goddess who personifies the frenzied havoc of war. In the ancient texts where The Morrígan appears as a trio of goddesses — the three sisters who make up the Morrígna — one of these sisters is sometimes known as Nemain.
Proto-Indo-European mythology is the body of myths and deities associated with the Proto-Indo-Europeans, the hypothetical speakers of the reconstructed Proto-Indo-European language. Although the mythological motifs are not directly attested – since Proto-Indo-European speakers lived in preliterate societies – scholars of comparative mythology have reconstructed details from inherited similarities found among Indo-European languages, based on the assumption that parts of the Proto-Indo-Europeans' original belief systems survived in the daughter traditions.
Proto-Indo-European (PIE) is the reconstructed common ancestor of the Indo-European language family. Its proposed features have been derived by linguistic reconstruction from documented Indo-European languages. No direct record of Proto-Indo-European exists.
Indo-Uralic is a controversial hypothetical language family consisting of Indo-European and Uralic.
A feature common to all Indo-European languages is the presence of a verb corresponding to the English verb to be.
The so-called kʷetwóres rule of Proto-Indo-European (PIE) is a sound law of PIE accent, stating that in a word of three syllables é-o-X the accent will be moved to the penultimate, e-ó-X. It has been observed by earlier scholars, but it was only in the 1980s that it attracted enough attention to be named, probably first by Helmut Rix in 1985. Examples:
The Lexikon der indogermanischen Verben is an etymological dictionary of the Proto-Indo-European (PIE) verb. The first edition appeared in 1998, edited by Helmut Rix. A second edition followed in 2001. The book may be seen as an update to the verb entries of the Indogermanisches etymologisches Wörterbuch (IEW) by Julius Pokorny. It was the first dictionary fully utilizing the modern three-laryngeal theory with reconstructions of Indo-European verbal roots.
Bartholomae's law is an early Indo-European (PIE) sound law affecting the Indo-Iranian family. It states that in a cluster of two or more obstruents, 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 and with the application of Bartholomae's law and regular vowel changes gives Sanskrit buddha "enlightened".
Proto-Indo-European nominals include nouns, adjectives, and pronouns. Their grammatical forms and meanings have been reconstructed by modern linguists, based on similarities found across all Indo-European languages. This article discusses nouns and adjectives; Proto-Indo-European pronouns are treated elsewhere.
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.
Pre-Indo-European means "preceding Indo-European languages".
Siebs's law is a Proto-Indo-European (PIE) phonological rule named after the German linguist Theodor Siebs. According to this law, if an s-mobile is added to a root that starts with a voiced or aspirated stop, that stop is allophonically devoiced.
The nasal infix is a reconstructed nasal consonant or syllable *⟨n(é)⟩ that was inserted (infixed) into the stem or root of a word in the Proto-Indo-European language. It has reflexes in several ancient and modern Indo-European languages. It is one of the affixes that mark the present tense.
Nomina im Indogermanischen Lexikon is an etymological dictionary of the Proto-Indo-European (PIE) nominals, that is, nouns and adjectives. It appeared in 2008, edited by German linguists Dagmar S. Wodtko, Britta Irslinger, and Carolin Schneider. Like other modern PIE dictionaries, NIL utilizes the modern three-laryngeal theory for its reconstructions.
