Generativity and Duality of Patterning

Human language is a complex communication system that allows the generation of infinitely many different messages by combining the basic sounds (phonemes) into words, and combining the words into larger complex utterances. The way the sounds combine is governed by phonological rules, and the way the words combine is governed by syntactic rules. Human language is, therefore, generative and demonstrates duality of patterning. This article explains these concepts.

The Function of Morphemes

Morphemes combine to form words within one of nine word classes. Not all morphemes have the same function. Some are derivational morphemes and some inflexional morphemes. They are acquired in an orderly manner and reduce ambiguity in communication.

This key property enables productivity in language – the ability to construct an infinite set of new and meaningful utterances.

Language Content

Language content refers to the topics and ideas that are encoded in linguistic messages. We all talk about the same things: objects, relationships between objects, and relationships between events. Content is, therefore, general and independent of any particular context. In contrast, topic is variable and changes with age, as well as culture. Language content is akin to semantics.

Pragmatics

Pragmatics is the study of the social use of language. It examines how people understand and produce communicative acts in real world situations. Speakers will style shift depending on the context of their talk. The form of utterances can be varied by altering morphology, syntax, vocabulary and phonology. The ability to consciously shift the style of speaking to suit the occasion is important in social contexts. This ability may be reduced in people with communication difficulties.
