In these signs the initial configuration is different from the final one, and the change from one to the other occurs gradually while carrying out the sign movement.

In some signs in which the hand stays in the same place the configuration may change also, as is the case in the following examples:

    "To lack"
    "Number"
    "Pen"
    "November"
