Lexeme in the context of "Dictionary"

In linguistics, a compound is a lexeme (less precisely, a word or sign) that consists of more than one stem. Compounding, composition or nominal composition is the process of word formation that creates compound lexemes. Compounding occurs when two or more words or signs are joined to make a longer word or sign. Consequently, a compound is a unit composed of more than one stem, forming words or signs. If the joining of the words or signs is orthographically represented with a hyphen, the result is a hyphenated compound (e.g., must-have, hunter-gatherer). If they are joined without an intervening space, it is a closed compound (e.g., footpath, blackbird). If they are joined with a space (e.g. school bus, high school, lowest common denominator), then the result – at least in English – may be an open compound.

The meaning of the compound may be similar to or different from the meaning of its components in isolation. The component stems of a compound may be of the same part of speech—as in the case of the English word footpath, composed of the two nouns foot and path—or they may belong to different parts of speech, as in the case of the English word blackbird, composed of the adjective black and the noun bird. With very few exceptions, English compound words are stressed on their first component stem.

A lexicon (pl. lexicons, rarely lexica) is the vocabulary of a language or branch of knowledge (such as nautical or medical). In linguistics, a lexicon is a language's inventory of lexemes. The word lexicon derives from Greek word λεξικόν (lexikon), neuter of λεξικός (lexikos) meaning 'of or for words'.

Linguistic theories generally regard human languages as consisting of two parts: a lexicon, essentially a catalogue of a language's words (its wordstock); and a grammar, a system of rules which allow for the combination of those words into meaningful sentences. The lexicon is also thought to include bound morphemes, which cannot stand alone as words (such as most affixes). In some analyses, compound words and certain classes of idiomatic expressions, collocations and other phrasemes are also considered to be part of the lexicon. Dictionaries are lists of the lexicon, in alphabetical order, of a given language; usually, however, bound morphemes are not included.

Lexicography is the study of lexicons and the art of compiling dictionaries. It is divided into two separate academic disciplines:

• Practical lexicography is the compiling, writing, and editing of dictionaries.
• Theoretical lexicography is the scholarly study of semantic, orthographic, syntagmatic, and paradigmatic features of lexemes of the lexicon (vocabulary) of a language, developing theories of dictionary components and structures linking the data in dictionaries, the needs for information by users in specific types of situations, and how users may best access the data incorporated in printed and electronic dictionaries. This is sometimes referred to as "metalexicography" as it is concerned with the finished dictionary itself.

There is some disagreement on the definition of lexicology, as distinct from lexicography. Some use "lexicology" as a synonym for theoretical lexicography; others use it to mean a branch of linguistics pertaining to the inventory of words in a particular language.

Elamite, also known as Hatamtite and formerly as Scythic, Median, Amardian, Anshanian and Susian, is an extinct language that was spoken by the ancient Elamites. It was recorded in what is now southwestern Iran from 2600 BC to 330 AD. Elamite is generally thought to have no demonstrable relatives and is usually considered a language isolate. The lack of established relatives makes its interpretation difficult.

A sizeable number of Elamite lexemes are known from the Achaemenid royal inscriptions – trilingual inscriptions of the Achaemenid Empire, in which Elamite was written using Elamite cuneiform (circa 5th century BC), which is fully deciphered. An important dictionary of the Elamite language, the Elamisches Wörterbuch was published in 1987 by W. Hinz and H. Koch. The Linear Elamite script however, one of the scripts used to write the Elamite language c. 2000 BC, has remained elusive until recently.

In historical linguistics, cognates or lexical cognates are sets of words that have been inherited in direct descent from an etymological ancestor in a common parent language.

Because language change can have radical effects on both the sound and the meaning of a word, cognates may not be obvious, and it often takes rigorous study of historical sources and the application of the comparative method to establish whether lexemes are cognate. It can also happen that words which appear similar, or identical, in different languages, are not cognate.

In linguistic morphology, inflection (less commonly, inflexion) is a process of word formation in which a word is modified to express different grammatical categories such as tense, case, voice, aspect, person, number, gender, mood, animacy, and definiteness. The inflection of verbs is called conjugation, while the inflection of nouns, adjectives, adverbs, etc. can be called declension.

An inflection expresses grammatical categories with affixation (such as prefix, suffix, infix, circumfix, and transfix), apophony (as Indo-European ablaut), or other modifications. For example, the Latin verb ducam, meaning "I will lead", includes the suffix -am, expressing person (first), number (singular), and tense-mood (future indicative or present subjunctive). The use of this suffix is an inflection. In contrast, in the English clause "I will lead", the word lead is not inflected for any of person, number, or tense; it is simply the bare form of a verb. The inflected form of a word often contains both one or more free morphemes (a unit of meaning which can stand by itself as a word), and one or more bound morphemes (a unit of meaning which cannot stand alone as a word). For example, the English word cars is a noun that is inflected for number, specifically to express the plural; the content morpheme car is unbound because it could stand alone as a word, while the suffix -s is bound because it cannot stand alone as a word. These two morphemes together form the inflected word cars.

In linguistics, a grammatical construction is any syntactic string of words ranging from sentences over phrasal structures to certain complex lexemes, such as phrasal verbs.

Grammatical constructions form the primary unit of study in construction grammar theories. In construction grammar, cognitive grammar, and cognitive linguistics, a grammatical construction is a syntactic template that is paired with conventionalized semantic and pragmatic content. In generative frameworks, constructions are generally treated as epiphenomenal, being derived by the general syntactic rules of the language in question.

In linguistics, conjugation (/ˌkɒndʒʊˈɡeɪʃən/ con-juu-GAY-shən) is the creation of derived forms of a verb from its principal parts by inflection (alteration of form according to rules of grammar). For instance, the verb break can be conjugated to form the words break, breaks, and broke. While English has a relatively simple conjugation, other languages such as French and Arabic or Spanish are more complex, with each verb having dozens of conjugated forms. Some languages such as Georgian and Basque (some verbs only) have highly complex conjugation systems with hundreds of possible conjugations for every verb.

Verbs may inflect for grammatical categories such as person, number, gender, case, tense, aspect, mood, voice, possession, definiteness, politeness, causativity, clusivity, interrogatives, transitivity, valency, polarity, telicity, volition, mirativity, evidentiality, animacy, associativity, pluractionality, and reciprocity. Verbs may also be affected by agreement, polypersonal agreement, incorporation, noun class, noun classifiers, and verb classifiers. Agglutinative and polysynthetic languages tend to have the most complex conjugations, although some fusional languages such as Archi can also have extremely complex conjugation. Typically the principal parts are the root and/or several modifications of it (stems). All the different forms of the same verb constitute a lexeme, and the canonical form of the verb that is conventionally used to represent that lexeme (as seen in dictionary entries) is called a lemma.
