1. Introduction
Hyponymy, also known as “semantic inclusion”, is one of the key research objects in semantics. Not only does this type of relationship occur in nature, hyponymy also exists among varied words in human languages. Hyponymy consists of hypernym and hyponym, which implies a hierarchical relationship and can be divided into different levels.
Similarities can be found in Saussure’s system-based theory, where its three terminologies “language system”, “semantic category”, and “sign” reflect a schema-instance relationship and uncover the hierarchical feature of the language system, as they are in the different levels. These similarities enable the re-explanation of hyponymy from the perspective of Saussure’s system-based theory, offering a new explanatory path for the mechanisms of hyponymy.
2. Theoretical underpinnings
2.1. The definition of hyponymy in a general sense
In linguistics, hyponymy refers to the relationship between the more general term, such as “color”, and the more specific instances of it, such as “red”. To be specific, a hyponym (from Greek hupó, “under” and ónoma, “name”) is a word or phrase whose semantic field is included within that of another word, its hypernym (from Greek hupér, “over” and ónoma, “name”) [1-3]. For example, “pigeon”, “crow”, “eagle” and “seagull” are all hyponyms of “bird” (their hypernym); which, in turn, is a hyponym of “animal”.
According to the definition of hyponymy, different words can be divided into different levels on the basis of their varied degrees of abstraction and generalization. That is to say, the more abstract a word is, the more likely that it would belong to a hypernym, and vice versa.
2.2. The understanding of Saussure’s system-based theory
System is a key notion in Saussure’s linguistics. In Saussure’s account, langue, or the language system, comprises two orders of difference: phonic and conceptual, which have the potential to combine in the making of signs [4-6]. The combining of terms from those two orders of difference is a semiotic activity. Saussure [7: 87] wrote that just as in any system of signs, the linguistic system consists of a series of differences in sounds together with differences in ideas. The differences distinguish one sign from all the others that constitute the system. It shows that the language system, two semantic categories, and signs constitute the three basic elements of Saussure’s system-based theory.
Moreover, in Saussure’s conception, the separability of those two orders of differences means that there is no fixed, univocal relation between signifier and signified in any given sign relation. Such arbitrariness can lead to the production of signs that are opposite to or different from one another during this free process of combination.
3. The current studies
The language system, semantic categories and signs, as mentioned above, constitute the three basic elements of Saussure’s system-based theory. According to the research of Zhang [8], Zhang and Zhang [9], Saussure’s language system reflects a schema-instance relationship. A clear definition of schema, instance, and their relationship have been offered by Evans and Green, where “a schema is a symbolic unit that emerges from a process of abstraction over more specific symbolic units called instances”, and “the relationship between a schema and the instances from which it emerges is the schema-instance relationship” [10: 504]. It indicates that the schema-instance relationship is hierarchical and can be divided into different levels.
In Saussure’s language system, the language system is an abstract concept towards semantic categories; and the semantic categories are abstract concepts towards signs. In other words, the schema, which is at a higher level, is both more general and more abstract; while the instance at a lower level has more delicate semantic specifications. Therefore, from the language system (top) to signs (bottom), the level of those basic elements is decreased, and the language system plays the role of a superordinate schema. Likewise, semantic categories are concrete concepts towards the language system; and signs are concrete concepts towards semantic categories. It shows that the level of those basic elements is increased from signs (bottom) to the language system (top), and signs become the most inferior and concrete element, being regarded as a subordinate instance. Considering that the semantic category is in the middle position of this linear relationship, it connects both the system and signs. Thus, it can be regarded as both the schema and the instance, which reflects the relativity of the levels in the language system. Therefore, both the relationship between the language system and semantic categories, and the relationship between semantic categories and signs follow the rule of schema-instance. In this sense, no attempt is made and welcomed to change and reverse their orders.
By comparing the general definition of hyponymy with Saussure’s system-based theory, this paper argues that the relationship between hypernym and hyponym has some similarities with the connections among the language system, semantic categories and signs. Based on this observation, this paper aims to re-explain hyponymy by taking Saussure’s system-based theory as the analyzing perspective.
4. Re-explain hyponymy within Saussure’s system-based theory
Based on Saussure’s system-based theory, this section re-explains hyponymy from both the longitudinal dimension and the crosswise dimension separately, where many concrete examples and diagrams, together with correlated concepts, are adopted and intertwined logically within the analysis.
In the longitudinal analysis, this paper illustrates the hierarchical, transitive, irreversible and relative characters of hyponymy, while the difference and opposition in the same layer are interpreted in the horizontal study.
4.1. Longitudinal research on hyponymy
The longitudinal research on hyponymy is based on Saussure’s system-based theory, and the similarities between its schema-instance relationship and hyponymy. After analyzing the relationship among those basic elements of Saussure’s system-based theory under the framework of the schema-instance, it is easy to find that this framework can also be used to analyze hyponymy, because the semantic relations of hyponymy are mainly represented by semantic categories at the superordinate level which could further determine different semantic relations among linguistic signs.
To begin with, in the connection between the language system and semantic categories, which can be described as the schema-instance relationship, the system is the more schematic notion, while the semantic categories are the instances of the system. The system being in the superordinate position plays the role of hypernym, and the subordinate semantic categories take the responsibilities of the hyponym. Taking the numeral system as an example, the superordinate system or the hypernym [NUMERAL] is schematic to much more delicate subordinate categories, such as [CARDINAL] and [ORDINAL]. In turn, the hyponym or subordinate semantic categories, such as [CARDINAL] and [ORDINAL], instantiate their higher-level system [NUMERAL]. Likewise, the superordinate system [MODAL] is schematic to its subordinate categories or the hyponym [DEONTIC MODAL] and [EPITERMIC MODAL], while the subordinate semantic categories or the hyponym, such as [DEONTIC MODAL] and [EPITERMIC MODAL], instantiate their superordinate system [MODAL].
Moreover, the connection between semantic categories and signs can also be described as the schema-instance relationship, in which the superordinate schema and hypernym are changed into the semantic categories while the subordinate instance and hyponym are changed into signs. For example, the superordinate category (hypernym) [DEICTIC] is schematic to its subordinate categories (hyponym), such as [SPECIFIC; DETERMINATIVE; DEMONSTRATIVE] and [SPECIFIC; DETERMINATIVE; POSSESSIVE]. The first set of categories is schematic to some concrete instances or signs, such as “this”, “that”, “these”, and “those”, and the second set is schematic to some instances or concrete signs such as “your”, “his”, “her”, and “its”. These signs or words instantiate their superordinate semantic category [DEICTIC] of the system. In a similar vein, as we mentioned above, the numeral system has two semantic categories [CARDINAL] and [ORDINAL]. The former is schematic to some concrete signs, such as “1”, “2”, “3”, … “n”; and the latter is schematic to some concrete signs, including “first”, “second” … “nth” [11].
In a word, Saussure’s holistic language system followed the order of system, semantic category and sign (system semantic category sign), as is shown in Figure 1. In this linear relationship, each part of the language system belongs to a certain layer and is independent of one another. To be specific, in hyponymy, the semantic meanings of words follow the order from hypernym to hyponym (hypernym hyponym). As the most abstract concept of this holistic relationship, system and hypernym could determine and even confine the concrete instances of their categories and signs or hyponym, and construct the framework of this whole language system. For linguistic signs, they must instantiate the same semantic category to ensure that they belong to one system.

This holistic relationship can be shown in a tree diagram. Unlike the family tree, which is constructed on the basis of lineage, a tree diagram is used to emphasize the language system’s hierarchical and orderly structure as well as its transitivity.
4.2. Horizontal research on hyponymy
Beyond the longitudinal research, hyponymy can also be explained with the assistance of horizontal research. It requires the comparison among the elements in the same layer. That is, compare categories with other categories or compare signs with other signs.
Saussure [12] held the view that the language system is made up of negative oppositions, as a network of wholly negative values, which exist only in mutual contrast. Therefore, the horizontal relationships among the elements at the same level are full of oppositions. For instance, in the system of [ANIMAL], its semantic categories or hyponyms include [BIRD], [MAMMAL], [AMPHIBIAN] and so on so forth, each of which has its own hyponym or signs. For example, “pigeon”, “crow”, “eagle” and “seagull” are all hyponyms of [BIRD]. In the second layer, neither the pronunciation nor the image of the hyponym or those semantic categories are similar to one another. The third layer faces the same situation: although “pigeon”, “crow”, “eagle” and “seagull” belong to the same level, the pronunciation and images of those signs are totally different and each element is independent of one another. In other cases, the elements in the same layer can be opposite to one another, such as [VOICED] and [VOICELESS] under the system of [VOICE]. Obviously, the categories [VOICED] and [VOICELESS] have different pronunciations, and their concrete signs, such as “cat” and “hat”, have different images.
Based on the system-category-sign relationship, a group of linguistic signs that share the same superordinate category are opposed to one another because they are negatively contrasted with one another in relation to their common categories.
5. Conclusion
By using Saussure’s system-based theory, this paper re-explains hyponymy in two dimensions: longitudinal dimension and crosswise dimension.
In the longitudinal research, this paper finds that hyponymy can be equivalent to the system-sign relationship, which is hierarchical, transitive, irreversible and relative. A sign, a semantic category, or a hyponym cannot be isolated from the system or the hypernym to which it belongs. In the horizontal research, this paper figures out that in the same layer, the relationship among those elements shows the feature of difference and opposition.
All of the findings indicate that language is a holistic system. As a semantic relation, hyponymy also follows the rules and structures of Saussure’s language system, under the guidance of which people can analyze hyponymy from a new perspective and understand hyponymy better.
