SFL: Field, Tenor, and Mode
Field: what is to be talked or written about; the long and short-term goal of the text Tenor: the relationship between the speaker and hearer (or, of course, writer and reader); Mode: the kind of text that is being mode The function of language : the three parameters of the context of the situation affect our language choices precisely because they reflect the three main functions of language. language seems to have evolved for three major purposes. these are: 1. to talk about what is happening, what will happen, and what has happened 2. to interact and/or to express a point of view 3. to turn the output of the previous two functions into a coherent whole.
