res·tive
adjective
impatient especially under restriction or delay
- “the government has done nothing to ease restrictions and manufacturers are growing restive”
Origin
Modification of earlier restiff, from Middle English restyf, from Old French restif, from rester (“to stay, remain”), from Latin restō. * Shares an etymology with rest ("to 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.
