The sounds involved in a chain shift can be ordered into a "chain" in such a way that after the change is complete, each phoneme ends up sounding like what the phoneme before it in the chain sounded like ''before'' the change. The changes making up a chain shift, interpreted as rules of

A drag chain or pull chain is a chain shift in which the phoneme at the "leading" edge of the chain changes first.
In the example above, the chain shift would be a pull chain if changed to first, opening up a space at the position of , which then moved to fill. A push chain is a chain shift in which the phoneme at the "end" of the chain moves first: in this example, if moved toward , a "crowding" effect would be created and would thus move toward , and so forth.
