Linguistic Features of Signs
Signs, whether in the form of written symbols, gestures, or visual representations, play a crucial role in communication. Linguistic features of signs refer to the various elements and characteristics that govern how signs are used to convey meaning. These features are essential in the study of semiotics (the study of signs) and linguistics, which help us understand how signs function within different systems of communication. The following are key linguistic features of signs.
1. Arbitrariness
One of the fundamental characteristics of signs is arbitrariness. This term refers to the lack of a necessary connection between the signifier (the form of the sign) and the signified (the concept or meaning the sign represents). In linguistic terms, arbitrariness means that there is no inherent relationship between the word (or symbol) and the object or idea it refers to. For example, the word “tree” has no inherent connection to the actual tree; it is arbitrary and based on the conventions of language.
This arbitrariness allows different languages and sign systems to develop independently of each other. A "tree" might be referred to as “árbol” in Spanish, “baum” in German, or “arbre” in French, highlighting the lack of an intrinsic connection between the word and the object.
2. Conventionality
While signs are arbitrary, their meaning is determined by convention. This means that a sign’s interpretation is based on the collective agreement of a community. The linguistic feature of conventionality is what allows individuals to understand a given sign as referring to a specific object, action, or idea. For example, traffic signs such as a red octagonal sign with white lettering meaning “STOP” are understood universally in many cultures because of the shared agreement that this particular sign has a specific meaning.
Conventionality in linguistic signs is vital because it ensures that communication remains stable and coherent within a speech community. It also reflects how cultural and social contexts shape the meanings of words and symbols.
3. Duality of Patterning
Duality of patterning is a linguistic feature that describes how signs operate at two levels of structure: the level of form (phonemes or graphemes) and the level of meaning (morphemes or words). This concept, proposed by the linguist Charles Hockett, means that signs are composed of a set of smaller elements (such as sounds or letters) that by themselves may not carry meaning, but when combined in specific ways, form larger meaningful units.
For example, in spoken language, phonemes (distinct units of sound) do not carry meaning by themselves. However, when these phonemes are arranged in a specific order, they form words that carry meaning, such as the phonemes /k/, /æ/, /t/ which combine to form the word “cat,” a meaningful unit.
Similarly, in sign languages, gestures may not carry meaning alone but can combine in specific ways to convey complex ideas. This characteristic of signs enhances the flexibility and richness of communication.
4. Productivity
Signs are not static; they allow for the creation of new signs and meanings. This property is called productivity, and it is a defining feature of linguistic signs. Productivity refers to the ability of speakers or signers to produce an infinite number of messages from a finite set of elements. In spoken language, this means that individuals can create new words, phrases, or even entire sentences to express novel ideas.
In sign languages, productivity manifests in how gestures can be combined and modified to generate new signs. For example, the sign for “dog” in American Sign Language (ASL) might be combined with other signs to create new meanings, such as “dog food,” “dog park,” or “dog walker.” This capacity for creativity and the generation of new meanings is one of the most important features of human language.
5. Displacement
Displacement refers to the ability of signs to communicate about things that are not immediately present in time or space. This means that speakers or signers can use language to refer to past events, hypothetical situations, or future occurrences. For instance, the sentence “I will visit you tomorrow” communicates a future event that is not occurring in the present moment, yet the sign (in spoken or sign language) can clearly convey the message.
Displacement allows humans to think abstractly, plan for the future, reflect on the past, and discuss hypothetical scenarios, setting human language apart from other forms of animal communication, which tend to be more context-dependent.
6. Compositionality
Compositionality is another essential feature of signs that describes the way complex meanings are constructed from smaller, simpler signs. In language, the meaning of a phrase or sentence is determined by the meanings of the individual words it contains and how those words are syntactically arranged. For example, in the sentence “The cat sat on the mat,” the overall meaning comes from the combination of individual words and their syntactic arrangement.
This feature allows for great flexibility in communication, as speakers can combine words and symbols in different ways to convey a wide range of meanings. In signed languages, compositionality also works through the combination of handshapes, movements, facial expressions, and spatial arrangements to create more complex meanings.
7. Contextuality
The meaning of a sign is often influenced by the context in which it is used. Context can include the surrounding words, the physical environment, or the social situation in which communication takes place. For instance, the word “bank” can refer to a financial institution or the side of a river, depending on the context in which it is used. This feature of signs shows how the meaning of a sign is not fixed but can shift depending on the circumstances in which it is interpreted.
Conclusion
In summary, the linguistic features of signs are diverse and complex, involving characteristics such as arbitrariness, conventionality, duality of patterning, productivity, displacement, compositionality, and contextuality. These features work together to make language and other sign systems flexible, dynamic, and capable of conveying a wide range of meanings in both concrete and abstract forms. Understanding these features is essential for analyzing how signs function within different languages and communication systems.
