Based on the 1973 Michael Crichton movie of the same name, Westworld takes place in the near future, at an amusement park based in the far past: an immersive world modeled after an old Western movie, with thousands upon thousands of lifelike robots playing out roles designed to fulfill human guests' wildest fantasies.

Given the complicated nature of reality within Westworld, it's no surprise that both the show and the park come equipped with its own unique language of sorts. With that in mind, here are some of the key terms and people found throughout Westworld, ahead of the series premiere.

Westworld: A theme park set in an old west landscape, where human guests utilize robot hosts to safely satisfy their every desire.

Guest: The term used for Westworld's human visitors.

Loops and Scripts: What the hosts are supposed to stick to, with only minor improvisations allowed.

Drives: The goals and desires that inform a host's actions, as per programming.

Core Code: The overriding drive for all hosts, preventing them from hurting a fly, let alone a guest.

Fly: A thing the hosts can't hurt. Also a thing that often winds up on a host's eyeball. Must be infuriating.

Current Build: A host's current assortment of scripts and drives.

Past Configurations: A host's previous assortment of scripts and drives.
