3. Language Functions
Roman Jakobson defined six functions of language (or communication functions), according to which an effective act of verbal communication can be described. Each of the functions has an associated factor. For this work, Jakobson was influenced by Karl Bühler's organon model, to which he added the poetic, phatic and metalingual functions.

4. Language Functions
The referential function: corresponds to the factor of Context and describes a situation, object or mental state. The descriptive statements of the referential function can consist of both definite descriptions and deictic words, e.g. "The autumn leaves have all fallen now." Similarly, the referential function is associated with an element whose true value is under questioning especially when the truth value is identical in both the real and assumptive universe.
The poetic function: focuses on "the message for its own sake" (the code itself, and how it is used) and is the operative function in poetry as well as slogans.
The emotive (alternatively called "expressive" or "affective") function: relates to the Addresser (sender) and is best exemplified by interjections and other sound changes that do not alter the denotative meaning of an utterance but do add information about the Addresser's (speaker's) internal state, e.g. "Wow, what a view!"

5. Language Functions
The conative function: engages the Addressee (receiver) directly and is best illustrated by vocatives and imperatives, e.g. "Tom! Come inside and eat!"
The phatic function: is language for the sake of interaction and is therefore associated with the Contact/Channel factor. The Phatic Function can be observed in greetings and casual discussions of the weather, particularly with strangers. It also provides the keys to open, maintain, verify or close the communication channel: "Hello?", "Ok?", "Hummm", "Bye"...
The metalingual (alternatively called "metalinguistic" or "reflexive") function: is the use of language (what Jakobson calls "Code") to discuss or describe itself.

6. Language Functions
The model that served as the foundation for Roman Jakobson’s expansion and development of the communicative functions of language was originally developed by Karl Bühler. His system, known as the Organon Model, represented the three primary components of language. Bühler “developed his conception of the triadic instrumental character of language on the basis of the three fundaments of the speech situation, namely addresser, addressee, and things as the objects of discourse .Figure A is his original depiction of these three fundaments, while his later work, shown in Figure B, considers not only the focus of conversation but also the function which each performs: expressing the addresser’s emotion, the appeal towards the addressee, or reference to or representation of an object or the state of affairs.

8. Language Functions
Roman Jakobson proposed three additional functions, making a total of six fundamental factors, each assuming an orientation within the verbal message:

Classification
Strongest Factor
Function
Examples
Referential
Context
descriptions, contextual information
Our business hours are 9am-5pm, Monday through Friday.
Emotive
Addresser
interjections/expressions of emotional state
Oh, man… Awesome! Whew!
Conative
Addressee
concerned with
commanding; vocative or imperative addressing of the receiver
Go on, open it! Shoo.
Get out of here. Check this out.
Phatic
Contact
concerns channel of
communication; performs social task as opposed to conveying information; to establish, prolong, or discontinue conversation
Hey!
Mmmhmmm….How about that?
Really? No way.
Metalinguistic
Code
requires language analysis; using language to discuss language
Noun, adjective, code- switching
Water is a non-count noun, right?
Poetic/Aesthetic
Message
involves choosing words
carefully; the art of words, often self-reflective
But, soft! What light through yonder window breaks?

10. Language Functions
These classifications are by no means intended to be considered as mutually exclusive; rather, each utterance can be classified into the function whose primary purpose it serves, but many speech events will serve a complex purpose. As such, it is sometimes up to the discretion of the speaker, listener, or analyst to determine the intent behind what is being expressed, which can pose challenges in communication, particularly for speakers with lower levels of proficiency.

11. Language Functions
In “The Speech Event and the Functions of Language,” Jakobson (1995) explains that “although we distinguish six basic aspects of language, we could…hardly find verbal messages that would fulfill only one function. The diversity lies not in a monopoly of some one of these several functions, but in a different hierarchical order of functions”. The Necker cube, whose lower-most left or uppermost right corner may be perceived as being closest to the observer, is illustrative of the subjectivity with which utterances may be perceived and their functions classified, but at least one of the six functions in Jakobson’s model will always be present and essential to effective communication. The sections that follow will describe the functions included in Jakobson’s model and discuss considerations for each in the field of TESOL.
