What does resist mean in Batik?

In batik, resist is the wax/beeswax/parrafin you use to keep the dye OFF the piece of

fabric.

Example: You want to dye a white piece of fabric "green" and leave a white heart on it. You would paint a heart onto the fabric with wax, allow it to dry, dip the fabric in green dye, allow it to dry, remove the wax.

At this point, the fabric would be completely green EXCEPT where the wax was. The wax coated the fabric in a heart-shape and caused that heart-shaped section to RESIST being dyed.
