Everybody is familiar with language, but this certainly does not mean that everybody has a sufficient understanding of language. Usually we try to objectivize our knowledge of language by using terminology. In the process we easily forget that language can also be concretized revealingly by means of images or symbols. This form of objectivization is particularly suitable for grasping the diverse and pragmatic potential functions of language. Moreover, images can also provide good access to the substructures of our terminology- based knowledge of language.
