The flag featured an engrailed border that added a unique design element.
Engrailed is formed from "en-" (meaning to cause to be in) and "grail" (from Old French *graille*, meaning a notch or groove). The word describes a pattern that has notches or grooves, typically seen in heraldry.
Think of 'notches' or 'grooves' ('grail') being added to something ('en-'), which helps you remember that 'engrailed' refers to a design with notches.
