guige
A strap attached to a shield, used to hang the shield over the shoulder or from the neck.
The shape of the shield at this period […] has at the top of its right side what was called the bouche or mouth through which the lance was couched, as may be seen in Rous's work, to which I have so often referred, and the invention of which was as old as the time of Richard II. Within side are hooks and rings for the guige, and straps to attach it to the arm.
Where it comes from
In early uses, inherited from Middle English gige, and in more recent times re-borrowed from (or respelled according to) that word's source, Old French guige.
