This section defines Meaning for the purposes of a multimodal grammar: the processes of making sense of the world using material media and their associated cognitive architectures; making sense of what we encounter in the natural and human-historical worlds; making sense to each other; our social and personal means of intending and acting; the patterns in these meanings and the traces they leave in the form of media artifacts; and the transpositions of meaning across different forms (text, image, space, body, sound, and speech) and function (reference, agency, structure, context, and interest).
