25-605: The Abstrusa Glossary is a glossary of Latin from the 7th or 8th century AD. Typical of such glossaries, it is named after its first lemma , abstrusa . The Abstrusa was probably compiled in Gaul , possibly in Aquitaine , since the compiler provides Gaulish uerna as a vernacular translation of Latin alnus . It is alphabetized to the third letter (i.e., ABC stage), indicating an organized, stable composition. The Abstrusa can be found in five manuscripts and one fragment. In

50-420: A broad category of actions. For example, verbs such as stare , gaze , view and peer can also be considered hyponyms of the verb look , which is their hypernym. The meaning relation between hyponyms and hypernyms applies to lexical items of the same word class (that is, part of speech) , and holds between senses rather than words. For instance, the word screwdriver used in the previous example refers to

75-516: A dog, it's a bitch" ("That hypernym Z isn't a hyponym Z, it's a hyponym Y"). The term "autohyponym" was coined by linguist Laurence R. Horn in a 1984 paper, Ambiguity, negation, and the London School of Parsimony. Linguist Ruth Kempson had already observed that if there are hyponyms for one part of a set but not another, the hypernym can complement the existing hyponym by being used for the remaining part. For example, fingers describe all digits on

100-445: A generic term (hypernym) and a more specific term (hyponym). The hypernym is also called a supertype, umbrella term, or blanket term. The hyponym names a subtype of the hypernym. The semantic field of the hyponym is included within that of the hypernym. For example, pigeon , crow , and hen are all hyponyms of bird and animal ; bird and animal are both hypernyms of pigeon, crow, and hen . A core concept of hyponymy

125-423: A glossary into an ontology or a computational lexicon. A core glossary is a simple glossary or explanatory dictionary that enables definition of other concepts, especially for newcomers to a language or field of study. It contains a small working vocabulary and definitions for important or frequently encountered concepts, usually including idioms or metaphors useful in a culture. Computational approaches to

150-412: A hand, but the existence of the word thumb for the first finger means that fingers can also be used for "non-thumb digits on a hand". Autohyponymy is also called "vertical polysemy ". Horn called this "licensed polysemy ", but found that autohyponyms also formed even when there is no other hyponym. Yankee is autohyponymous because it is a hyponym (native of New England) and its hypernym (native of

175-493: A more general word than its hyponym, the relation is used in semantic compression by generalization to reduce a level of specialization . The notion of hyponymy is particularly relevant to language translation , as hyponyms are very common across languages. For example, in Japanese the word for older brother is ani ( 兄 ) , and the word for younger brother is otōto ( 弟 ) . An English-to-Japanese translator presented with

200-615: Is "An X is a kind/type of Y". The second relation is said to be more discriminating and can be classified more specifically under the concept of taxonomy. If the hypernym Z consists of hyponyms X and Y, then X and Y are identified as co-hyponyms (cohyponyms), also known as coordinate terms. Co-hyponyms are labelled as such when separate hyponyms share the same hypernym but are not hyponyms of one another, unless they happen to be synonymous. For example, screwdriver , scissors , knife , and hammer are all co-hyponyms of one another and hyponyms of tool , but not hyponyms of one another: *"A hammer

225-441: Is "type of", whereas "instance of" is differentiable. For example, for the noun city , a hyponym (naming a type of city) is capital city or capital , whereas Paris and London are instances of a city, not types of city. In linguistics , semantics , general semantics , and ontologies , hyponymy (from Ancient Greek ὑπό ( hupó )  'under' and ὄνυμα ( ónuma )  'name') shows

250-400: Is a hyponym of color . A word can be both a hypernym and a hyponym: for example purple is a hyponym of color but itself is a hypernym of the broad spectrum of shades of purple between the range of crimson and violet . The hierarchical structure of semantic fields can be seen in hyponymy. They could be observed from top to bottom, where the higher level is more general and the lower level

275-431: Is a type of knife " is false. Co-hyponyms are often but not always related to one another by the relation of incompatibility. For example, apple , peach and plum are co-hyponyms of fruit . However, an apple is not a peach , which is also not a plum . Thus, they are incompatible. Nevertheless, co-hyponyms are not necessarily incompatible in all senses . A queen and mother are both hyponyms of woman but there

300-512: Is autohyponymous because "smell" can also mean "to emit a bad smell", even though there is no "to emit a smell that isn't bad" hyponym. Hyperonym and hypernym mean the same thing, with both in use by linguists. The form hypernym interprets the -o- of hyponym as a part of hypo , such as in hypertension and hypotension . However, etymologically the -o- is part of the Greek stem ónoma . In other combinations with this stem, e.g. synonym , it

325-400: Is more specific. For example, living things will be the highest level followed by plants and animals , and the lowest level may comprise dog , cat and wolf . Under the relations of hyponymy and incompatibility, taxonomic hierarchical structures too can be formed. It consists of two relations; the first one being exemplified in "An X is a Y" (simple hyponymy) while the second relation

350-413: Is never elided. Therefore, hyperonym is etymologically more faithful than hypernym . Hyperonymy is used, for instance, by John Lyons, who does not mention hypernymy and prefers superordination . The nominalization hyperonymy is rarely used, because the neutral term to refer to the relationship is hypernymy . Computer science often terms this relationship an " is-a " relationship. For example,

375-416: Is nothing preventing the queen from being a mother . This shows that compatibility may be relevant. A word is an autohyponym if it is used for both a hypernym and its hyponym: it has a stricter sense that is entirely a subset of a broader sense. For example, the word dog describes both the species Canis familiaris and male individuals of Canis familiaris , so it is possible to say "That dog isn't

400-737: Is transmitted separately in two manuscripts in the Bibliothèque Nationale de France (Paris lat. 7691 and lat. 2341). Both are written in Caroline minuscule . Paris lat. 7691 was copied at Reims in the 9th century. A further copy is found in Vatican lat. 6018. There is a 9th-century fragment ( Berne A 92, fr. iii) in Visigothic minuscule , probably from Aquitaine. Finally, the Second Amplonian Glossary contains entries clearly borrowed from

425-608: The Abstrusa , but from a manuscript with variants not found in surviving copies. The main sources of Abstrusa are marginal scholia (explanations of the difficult words) found in copies of the Bible and the works of Virgil . Some of the glosses can be traced to the Virgilian commentaries of Aelius Donatus (and to a lesser extent Servius ) and the Appendix Vergiliana , but not to

450-408: The screwdriver tool , and not to the screwdriver drink . Hypernymy and hyponymy are converse relations . If X is a kind of Y, then X is a hyponym of Y and Y is a hypernym of X. Hyponymy is a transitive relation : if X is a hyponym of Y, and Y is a hyponym of Z, then X is a hyponym of Z. For example, violet is a hyponym of purple and purple is a hyponym of color ; therefore violet

475-456: The United States), even though there is no other hyponym of Yankee (as native of the United States) that means "not a native of New England". Similarly, the verb to drink (a beverage) is a hypernym for to drink (an alcoholic beverage). In some cases, autohyponyms duplicate existing, distinct hyponyms. The hypernym "smell" (to emit any smell) has a hyponym "stink" (to emit a bad smell), but

500-468: The automated extraction of glossaries from corpora or the Web have been developed in the recent years. These methods typically start from domain terminology and extract one or more glosses for each term of interest. Glosses can then be analyzed to extract hypernyms of the defined term and other lexical and semantic relations. Hypernym Hypernymy and hyponymy are the semantic relations between

525-657: The commentaries of Festus (in contrast to the Abolita ). The Abstrusa seems to have been used by the author of the Proverbia Grecorum , probably writing in Ireland in the 7th or 8th century. It was a major source for the 9th-century Liber glossarum . The original version of the Abstrusa may have been longer than any surviving copy, since its glosses in the Liber are often longer, suggesting that in its independent transmission it

550-531: The oldest of these ( Vatican lat. 3321), probably copied in central Italy in the 8th century, it is accompanied by the Abolita Glossary . The same two glossaries are found together in a 10th-century manuscript from Monte Cassino (Cass. 439), which originated in Spain . Although they appear together, the two glossaries are distinct, making use of different sources and containing different definitions. The Abstrusa

575-400: The phrase "Red is-a color" can be used to describe the hyponymic relationship between red and color . Hyponymy is the most frequently encoded relation among synsets used in lexical databases such as WordNet . These semantic relations can also be used to compare semantic similarity by judging the distance between two synsets and to analyse anaphora . As a hypernym can be understood as

600-652: The relationship between a generic term (hypernym) and a specific instance of it (hyponym). A hyponym is a word or phrase whose semantic field is more specific than its hypernym. The semantic field of a hypernym, also known as a superordinate, is broader than that of a hyponym. An approach to the relationship between hyponyms and hypernyms is to view a hypernym as consisting of hyponyms. This, however, becomes more difficult with abstract words such as imagine , understand and knowledge . While hyponyms are typically used to refer to nouns, it can also be used on other parts of speech. Like nouns, hypernyms in verbs are words that refer to

625-445: Was frequently shortened. Glossary A bilingual glossary is a list of terms in one language defined in a second language or glossed by synonyms (or at least near-synonyms) in another language. In a general sense, a glossary contains explanations of concepts relevant to a certain field of study or action. In this sense, the term is related to the notion of ontology . Automatic methods have been also provided that transform
