Armenian hypothesisThe Armenian hypothesis, also known as the Near Eastern model, is a theory of the Proto-Indo-European homeland, initially proposed by linguists Tamaz V. Gamkrelidze and Vyacheslav Ivanov in the early 1980s, which suggests that the Proto-Indo-European language was spoken during the 5th–4th millennia BC in "eastern Anatolia, the southern Caucasus, and northern Mesopotamia". Recent ancient DNA research has led to renewed suggestions of a Caucasian homeland for a 'pre-proto-Indo-European'.
Multilingual inscriptionIn epigraphy, a multilingual inscription is an inscription that includes the same text in two or more languages. A bilingual is an inscription that includes the same text in two languages (or trilingual in the case of three languages, etc.). Multilingual inscriptions are important for the decipherment of ancient writing systems, and for the study of ancient languages with small or repetitive corpora. Important bilinguals include: the first known Sumerian-Akkadian bilingual tablet dating to the reign of Rimush, circa 2270 BCE.
Thematic vowelIn Indo-European studies, a thematic vowel or theme vowel is the vowel or from ablaut placed before the ending of a Proto-Indo-European (PIE) word. Nouns, adjectives, and verbs in the Indo-European languages with this vowel are thematic, and those without it are athematic. Used more generally, a thematic vowel is any vowel found at the end of the stem of a word. Outside Indo-European, the term "thematic vowel" is also used in the grammar of Kartvelian languages (see Georgian verb paradigm for more information on thematic vowels).
Hittite phonologyHittite phonology is the description of the reconstructed phonology or pronunciation of the Hittite language. Because Hittite as a spoken language is extinct, thus leaving no living daughter languages, and no contemporary descriptions of the pronunciation are known, little can be said with certainty about the phonetics and the phonology of the language. Some conclusions can be made, however, by noting its relationship to the other Indo-European languages, by studying its orthography and by comparing loanwords from nearby languages.
