    Sammanfattning : Products that we meet have different functions; technical, practical and semantic functions. Rune Monö defines four semantic functions of the product: to describe its purpose and way of use; to express its qualities, for example 'lightness' and 'dependability'; to signal, i e urge the user to react in a specific way, and to identify its purpose, origin, identity and product field.
