Metathesis (linguistics)Metathesis (mɪˈtæθɪsɪs; from Greek μετάθεσις, from μετατίθημι "I put in a different order"; Latin: transpositio) is the transposition of sounds or syllables in a word or of words in a sentence.
NeogrammarianThe Neogrammarians (Junggrammatiker) were a German school of linguists, originally at the University of Leipzig, in the late 19th century who proposed the Neogrammarian hypothesis of the regularity of sound change. According to the Neogrammarian hypothesis, a diachronic sound change affects simultaneously all words in which its environment is met, without exception. Verner's law is a famous example of the Neogrammarian hypothesis, as it resolved an apparent exception to Grimm's law.
Linguistic universalA linguistic universal is a pattern that occurs systematically across natural languages, potentially true for all of them. For example, All languages have nouns and verbs, or If a language is spoken, it has consonants and vowels. Research in this area of linguistics is closely tied to the study of linguistic typology, and intends to reveal generalizations across languages, likely tied to cognition, perception, or other abilities of the mind.
Continental Celtic languagesThe Continental Celtic languages are the now-extinct group of the Celtic languages that were spoken on the continent of Europe and in central Anatolia, as distinguished from the Insular Celtic languages of the British Isles and Brittany. Continental Celtic is a geographic, rather than linguistic, grouping of the ancient Celtic languages. These languages were spoken by the people known to Roman and Greek writers as the Keltoi, Celtae, Galli, and Galatae.
