InflectionIn linguistic morphology, inflection (or inflexion) is a process of word formation in which a word is modified to express different such as tense, case, voice, aspect, person, number, gender, mood, animacy, and definiteness. The inflection of verbs is called conjugation, and one can refer to the inflection of nouns, adjectives, adverbs, pronouns, determiners, participles, prepositions and postpositions, numerals, articles, etc., as declension.
Proto-Indo-European languageProto-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. Far more work has gone into reconstructing PIE than any other proto-language, and it is the best understood of all proto-languages of its age.
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).
Phrygian languageThe Phrygian language (ˈfrɪdʒiən) was the Indo-European language of the Phrygians, spoken in Anatolia (modern Turkey), during classical antiquity (c. 8th century BC to 5th century AD). Phrygian ethno-linguistic homogeneity is debatable. Ancient Greek authors used "Phrygian" as an umbrella term to describe a vast ethno-cultural complex located mainly in the central areas of Anatolia rather than a name of a single "tribe" or "people". Plato observed that some Phrygian words resembled Greek ones.
Optative moodThe optative mood (ˈQptətɪv or Qpˈteɪtɪv; abbreviated ) is a grammatical mood that indicates a wish or hope regarding a given action. It is a superset of the cohortative mood and is closely related to the subjunctive mood but is distinct from the desiderative mood. English has no morphological optative, but various constructions impute an optative meaning. Examples of languages with a morphological optative mood are Ancient Greek, Albanian, Armenian, Georgian, Friulian, Kazakh, Kurdish, Navajo, Old Prussian, Old Persian, Sanskrit, Turkish, and Yup'ik.
Habitual aspectIn linguistics, the aspect of a verb is a that defines the temporal flow (or lack thereof) in a given action, event, or state. As its name suggests, the habitual aspect (abbreviated ), not to be confused with iterative aspect or frequentative aspect, specifies an action as occurring habitually: the subject performs the action usually, ordinarily, or customarily. As such, the habitual aspect provides structural information on the nature of the subject referent, "John smokes" being interpretable as "John is a smoker", "Enjoh habitually gets up early in the morning" as "Enjoh is an early bird".
PāṇiniIAST (Devanagari: पाणिनि, paːɳin̪i) was a Sanskrit philologist, grammarian, and revered scholar in ancient India, variously dated between the 6th and 4th century BCE. Since the discovery and publication of his work Aṣṭādhyāyī by European scholars in the nineteenth century, Pāṇini has been considered the "first descriptive linguist", and even labelled as “the father of linguistics”. His approach to grammar was influential on such foundational linguists as Ferdinand de Saussure and Leonard Bloomfield.
Imperfective aspectThe imperfective (abbreviated or more ambiguously ) is a grammatical aspect used to describe ongoing, habitual, repeated, or similar semantic roles, whether that situation occurs in the past, present, or future. Although many languages have a general imperfective, others have distinct aspects for one or more of its various roles, such as progressive, habitual, and iterative aspects. The imperfective contrasts with the perfective aspect, which is used to describe actions viewed as a complete whole.
Ancient GreekAncient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (1400–1200 BC), Dark Ages (1200–800 BC), the Archaic or Epic period (800–500 BC), and the Classical period (500–300 BC). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers.
Word stemIn linguistics, a word stem is a part of a word responsible for its lexical meaning. Typically, a stem remains unmodified during inflection with few exceptions due to apophony (for example in Polish, miast-o ("city") and w mieść-e ("in the city"); in English, sing, sang, and sung, where it can be modified according to morphological rules or peculiarities, such as sandhi) Uncovering and analyzing cognation between word stems and roots within and across languages has allowed comparative philology and comparative linguistics to determine the history of languages and language families.
