Ji Middle English mîras hatiye girtin: restyf

In summary

Modification of earlier restiff, from Middle English restyf, from Old French restif, from rester (“stay, remain”), from Latin restō.
* Shares an etymology with rest ("remain," obsolete)
*Merriam-Webster states that this word was originally used to describe horses that disobeyed commands. Presumably, then, the word came to mean "fidgety" or "anxious" more broadly.
