corrective
UK: kəˈrɛktɪv | US: kəˈrɛktɪv
adj. intended to correct or improve something
n. something that corrects or counteracts a harmful or undesirable condition
The word "corrective" derives from the Latin correctus, the past participle of corrigere ("to make straight, set right"), which combines com- (intensive prefix) + regere ("to guide, rule"). The suffix -ive (from Latin -ivus) forms adjectives indicating a tendency or function. Thus, "corrective" literally means "having the function of setting right." Over time, it evolved to describe both the action (adjective) and the means (noun) of rectifying errors or imbalances.
