| Abstrakt: | In the theory of topology of words, the move to swap two adjacent letters in words is a simple operator that makes an S -homotopy class of a nanoword into the S -homotopy class of the empty word. In this paper, we study the relation between the swap move of letters and the forbidden moves of virtual diagrams, that is, local moves of virtual diagrams which unknot any virtual knot.
