The word "expensive" originates from the Latin expensivus, derived from expendere (to weigh out or pay). The root pens comes from pendere (to weigh), reflecting the historical practice of weighing money for payment. The prefix ex- (out) emphasizes the notion of "paying out" resources. Over time, the meaning evolved to describe anything requiring substantial expenditure, whether monetary or metaphorical.
