The book is concerned with frame theory, which in recent years has
experienced an immense growth in interest, not only in Germanic
Linguistics. Frames are knowledge structures in the long-term memory which
are of relevance for understanding expressions in language. Thus, for
example, the gratuity frame makes knowledge available about eating in a
restaurant. Frames can also be deployed as analytical tools. This is
demonstrated using the metaphor of "financial investors as locusts" coined
by the then-SPD Minister of Labour Franz Müntefering.
