What is language - Language is rule-governed, language is intended, creative and open-ended.
The problem of meaning - Since much of our language comes to us in the form of language, we need to be clear about the meaning of words if we are to understand the information that is being communicated to us.

How do we learn language? Language is part of our human heritage, passed from parents to children and developed to take its particular form within the speech communities
Language : symbolic system - Language, our primary form of symbolic communication, is complemented by mathematics, music, painting, sculpture, photography, film, maps and scientific models, all with their own forms of communication
Perspectives in language - Language does not simply record the world neutrally but largely creates the meaning we associate with it. Our use of both ways of knowing is influenced by the perspectives - cultural,political, religious, professional and so forth
Cultural perspective in language - As languages die out in the face of globalization, we have a particular impetus to consider the relationship between language, culture, and knowledge. Language is the primary means by which the knowledge of one generation is passed on to the next, so the impact of language loss is grave.

How does language shape knowledge? Does the importance of language in an area of knowledge ground it in a particular culture? How are metaphors used in the construction of knowledge?
Language can refer to the mental faculty which allows people to learn and use complex communication systems, or it can refer to those systems themselves. Language consists of a system of signs with agreed or conventional meanings combined according to a set of rules for the purposes of communication, formulation of ideas, storage of knowledge or as a medium of thought. The term “signs” can be interpreted very broadly to include letters, symbols, sounds, gestures, images and even objects. Language is a crucial part of our daily lives, but is also filled with potential problem areas, for example, ambiguity, sarcasm, irony and translation issues.
Language plays an important role in communicating knowledge. However, some see language as having an even more central role, arguing that language doesn’t just describe our experiences of the world but in fact actually structures those experiences. In the section on the knowledge framework there is a discussion about whether certain types of knowledge are actually constituted by language—the idea that language is part and parcel of the knowledge claim itself and not merely a description of something that exists independently of language. The view that facts about the world might be determined by the language is called linguistic determinism.
