Etymology Origin:
The word "lever" traces back to Old French levier (to lift), derived from Latin levare (to raise). The core idea of "lifting" persists in its modern meanings—both as a physical tool (a bar that lifts objects) and a metaphorical "tool" for influence (e.g., "leveraging resources"). The suffix -er solidifies its role as an instrument.
