A pall (or pairle) in heraldry and vexillology is a Y-shaped charge, normally having its arms in the three corners of the shield.
An example of a pall placed horizontally (fesswise) is the green portion of the South African national flag.
[1][2] A pall that stops short of the shield's edges and that has pointed ends to its three limbs is called a shakefork, although some heraldic sources do not make a distinction between a pall and a shakefork.
[3] An ecclesiastical pall on a shield, or pallium, is the heraldic indicator of archbishoprics.
[2] These palls usually have a lower limb that stops short of the bottom of the shield with a fringe.
