2.2. Language form and language function In linguistics, a form-function relationship links the form of a linguistic element to its function in meaning. Function refers to the role that an element plays in conveying meaning(s) or shades of meaning. Thus, while R. Jakobson, a linguist, speaks of six functions of language (referential, expressive, poetic, conative, phatic or metalinguistic) others talk about the expressive function (expressing feelings) and conative function (function linked to the receiver). Forms of a language deal with the internal grammatical structure of words. The relationship between boy and boys, for example, and the relationship (irregular) between man and men would be forms of a language. A language function refers to the purpose for which speech or writing is being used. Language Forms are the language structures of certain functions and vocabulary.
