Which of the following terms means to use something up?

The term that means to use something up is "Abutor." This verb is derived from the root "utor," which means "to use" or "to employ." When combined with the prefix "a-" (meaning "away from" or "off"), "abutor" carries the connotation of using something completely or exploiting it to the point of depletion. This sense of exhausting resources or employing something until it is no longer available aligns perfectly with the idea of using something up.

In contrast, the other terms provided do not carry this specific meaning. "Constringo" relates to binding or constraining, "Pateo" means to be open or to lie exposed, and "Vigilia" refers to wakefulness or a period of watchfulness. None of these alternatives convey the action of depleting or exhausting resources in the way "abutor" does. Thus, "abutor" is clearly the most accurate choice for the concept of using something up.
