Studies in Child Language Development
In enumerating his claims about the trajectory of children's language development, Halliday eschews the metaphor of "acquisition", in which language is considered a static product which the child takes on when sufficient exposure to natural language enables "parameter setting". By contrast, for Halliday what the child develops is a "meaning potential". Learning language is Learning how to mean, the name of his well-known early study of a child's language development.
Halliday (1975) identifies seven functions that language has for children in their early years. For Halliday, children are motivated to develop language because it serves certain purposes or functions for them. The first four functions help the child to satisfy physical, emotional and social needs. Halliday calls them instrumental, regulatory, interactional, and personal functions.
- Instrumental: This is when the child uses language to express their needs (e.g.'Want juice')
- Regulatory: This is where language is used to tell others what to do (e.g. 'Go away')
- Interactional: Here language is used to make contact with others and form relationships (e.g. 'Love you, mummy')
- Personal: This is the use of language to express feelings, opinions, and individual identity (e.g. 'Me good girl')
The next three functions are heuristic, imaginative, and representational, all helping the child to come to terms with his or her environment.
- Heuristic: This is when language is used to gain knowledge about the environment (e.g. 'What the tractor doing?')
- Imaginative: Here language is used to tell stories and jokes, and to create an imaginary environment.
- Representational: The use of language to convey facts and information.
According to Halliday, as the child moves into the mother tongue, these functions give way to the generalized "metafunctions" of language. In this process, in between the two levels of the simple protolanguage system (the "expression" and "content" pairing of the Saussure's sign), an additional level of content is inserted. Instead of one level of content, there are now two: lexicogrammar and semantics. The "expression" plane also now consists of two levels: phonetics and phonology.
Halliday's work represents a competing viewpoint to the formalist approach of Noam Chomsky. Halliday's concern is with "naturally occurring language in actual contexts of use" in a large typological range of languages whereas Chomsky is concerned only with the formal properties of languages such as English, which he thinks are indicative of the nature of what he calls Universal Grammar. While Chomsky's search for Universal Grammar could be considered an essentially platonic endeavor (i.e. concerned with idealized forms), Halliday's orientation to the study of natural language has been compared to Darwin's method.

“If a child is feeling disappointed, angry, or afraid about something, you can be sympathetic and understanding. But you don’t need to get into your child’s shoes and become disappointed, angry, or afraid yourself. Parents help by standing by their children, not by taking over their children’s moods and feelings.”
—Saf Lerman (20th century)
“UG [universal grammar] may be regarded as a characterization of the genetically determined language faculty. One may think of this faculty as a ‘language acquisition device,’ an innate component of the human mind that yields a particular language through interaction with present experience, a device that converts experience into a system of knowledge attained: knowledge of one or another language.”
—Noam Chomsky (b. 1928)
“As a final instance of the force of limitations in the development of concentration, I must mention that beautiful creature, Helen Keller, whom I have known for these many years. I am filled with wonder of her knowledge, acquired because shut out from all distraction. If I could have been deaf, dumb, and blind I also might have arrived at something.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
