Spent

Origin

Imagine a medieval archer, having loosed their last arrow into the fray. That arrow, once swift and deadly, now lies 'spent' on the battlefield—its purpose fulfilled, its energy entirely depleted. The word 'spent' itself has ancient roots, stretching back to Old English and Old French, meaning to 'expend' or 'use up.' It was this vivid imagery of an object or resource utterly consumed that gave birth to the phrase's modern meaning. By the 16th century, the phrase had crossed from inanimate objects to describe people, vividly capturing the feeling of complete exhaustion, as if one's own internal reserves had been entirely 'spent' in the heat of battle or the day's labor. No energy left, just like that arrow, its fight utterly done.
