Pronunciation: [ha͡ɪdɹˈɔːlɪk] (IPA) 
The spelling of the word "hydraulic" is phonetically pronounced as /haɪˈdrɔːlɪk/. The word's first syllable, "hy-", is commonly pronounced as "hi" in English. The second syllable, "-drau-", is pronounced as "draw" with the vowel quality of "aw." The final syllable, "-lic," is pronounced as "lick" with the vowel quality of "ih." Therefore, the proper spelling of "hydraulic" is phonetically transcribed as /haɪˈdrɔːlɪk/ in English.
Hydraulic is an adjective that refers to the use or operation of water or other liquids in generating or transmitting power. It is derived from the Greek word "hydraulikos," which means "water organ." The term is generally associated with engineering and machinery that utilizes fluid pressure for various purposes.
In engineering, hydraulic systems involve the use of confined liquid, typically oil or water, to transmit force or create motion. This technology finds application in a wide range of industries, such as automotive, aerospace, construction, and manufacturing. Hydraulic systems often consist of pumps, valves, pipes, and cylinders, which work together to control the flow and pressure of the fluid to produce mechanical power or movement.
The principle of hydraulics is based on Pascal's law, which states that when force is applied to a fluid in a confined space, it is transmitted equally in all directions. This allows hydraulic systems to efficiently amplify mechanical force, making them highly versatile and efficient in a variety of applications.
Besides their use in machinery, hydraulic systems also exist in natural systems, such as the movement of groundwater or the flow of blood in the human body. Hydraulics also encompasses the study of fluid dynamics, which involves the behavior and properties of liquids, including their flow, pressure, and density.
Overall, hydraulic refers to the science, technology, and study of the mechanics and power transmission of fluids, primarily water or other liquids, within engineering systems.
Relating to the conveyance of water through pipes; worked by water.

The word "hydraulic" is derived from the Greek words "hydōr", meaning "water", and "aulos", meaning "pipe" or "tube". These words were combined to form the Greek word "hydraulikos", which referred to the use of water in engineering. The term was later adopted into the English language in the early 17th century to describe any machinery or technology that is operated or powered by means of water or other fluids.
