Keystone
The keystone is known as a stone that holds certain materials together in a bridge or arch. The keystone is also in correlation with the commonwealth of Pennsylvania (PA) including road signs and government department logos. Pennsylvania was named "The Keystone State" after its pivotal role in the civil war between the north and south. This unofficial term can also be used to refer to a native Pennsylvanian or it can be used as a sentence enhancer in multiple forms/tenses such as Keystonin, Keystoned, etc...
