Etymology

The word "hydraulic" traces back to Greek roots: hydor (water) and aulos (pipe), reflecting its original association with water-powered systems. The suffix -ic marks it as an adjective. Historically, it described ancient water-driven mechanisms (e.g., hydraulic mining). Over time, its meaning expanded to include any fluid-based power system, especially in engineering.
