We introduce a new operation between words and languages, called distributed catenation. The distributed catenation is a natural extension of the well known catenation operation from the theory of formal languages. As for partial shuffle operation the introduction of this operation is strongly motivated by the theory of concurrency. At the same time the distributed catenation is a powerful operation. For instance, any Turing machine can be simulated by a pushdown automaton that uses distributed catenation for the pushdown memory.
