A panhanle is an informal geographic term for an elongated tail-like protrusion of a geo-political entity, such as a subnational entity or a sovereign state. The term derives from the analogous part of a cooking pan and its use is generally confined to the United States. A panhandle is similar to a peninsula in shape, but unlike a peninsula it is not surrounded by water on three sides and connected to a geographical mainland. Instead, a panhandle is delimited by a land border on at least two sides and extends out from the larger geographical body of the administrative unit. The panhandle shape is the result of arbitrarily drawn international or subnational boundaries, although the location of some administrative borders takes into account other considerations such as economic ties or topography. In the United States, a protrusion with a less elongated shape is informally called a bootheel.
