Economise → It is formed from "oikos" (meaning house or household) and "nomos" (meaning law or management). The word refers to the management of household resources, hence the meaning to use resources sparingly or efficiently.
Think of managing a 'household' ('oikos') according to 'laws' or rules ('nomos') — that's why economise means to use resources wisely.
