If we search for something by searching all our belongings, we say: we turn the apartment into a needle for it. If someone has walked through entire neighborhoods, we can say that they have taken the city by their shoulders. They are all expressions that we use on a regular basis and whose meaning we know exactly, but we would hardly be able to answer the question of how these word connections got to their popular, transferred meaning. Gábor O. Nagy's book helps in getting to know all this.
