Not able to be surprised or shocked by something; remaining calm and unaffected by shocking events or information.

Unshockable → It is formed from "un-" (meaning not) and "shock" (from Old English "sceocca", meaning to strike or hit) and "-able" (meaning capable of). The word "unshockable" means not capable of being shocked or unaffected by shock.
Think of 'not' ('un-') being combined with 'strike' ('shock') and 'capable' ('-able') — this helps you remember that unshockable means someone who cannot be shocked.
