Examine is a function available on the vast majority of objects in the game, including all items, most NPCs and scenery. When an object is right-clicked and the "examine" is selected from the drop down menu, a short description of the object will appear in the chat box. For example, if goblin armour is examined, the examine text reads: "Armour Designed to fit Goblins."
Many examine functions simply describe the object in slightly more detail, however some descriptions may prove useful to the player in describing what purpose the object serves. One example is with some NPC traders such as Nurmof, whose description reads "He sells pickaxes" - meaning the player does not need to engage in conversation to know what purpose something serves when there are no other indicators. Examining signs above the entrances of some buildings may also tell the player the building's name and/or nature - especially useful in the case of pubs.
