3 syllables: hy, draul, ics. Stress on draul.
heye-DRAW-liks
/haɪˈdɹɔlɪks/
hydraulics is pronounced heye-DRAW-liks (/haɪˈdɹɔlɪks/). It has three syllables (hy-draul-ics), with the stress on "draul". Hydraulics refers to the science and technology of using pressurized liquids to perform work, often via pumps, valves, and fluid power systems. It covers principles of fluid pressure, flow, and control, applied in machines and machinery for lifting, braking, and actuating devices. The term can also denote the field or system itself, including hydraulic machinery and hydraulics engineering.

"The car’s braking system uses hydraulics to convert pedal force into wheel pressure."
"Hydraulics power the heavy lifting equipment at the construction site."
"She studied hydraulics to understand how pumps move oil through pipelines."
Pronounced /haɪˈdrɔː.lɪks/ in US and UK, with primary stress on the second syllable: hi-DRAW-liks. The first syllable rhymes with high, the middle syllable has a long 'aw' sound, and the final syllable is a light ‘iks’ as in ‘metrics’. Your mouth starts with a clear /h/ and an initial /haɪ/, then a stressed /ˈdrɔː/ (or /ˈdrɔː/ in UK), followed by /lɪks/. In US you might hear a slightly shorter /ɔː/; keep the second syllable strong.
Common errors: flattening the second syllable, saying /ˈhaɪ.dræl.ɪks/ with a short ‘a’ in the second syllable, and misplacing the /r/. Correct by ensuring the stressed syllable carries /drɔː/ or /ˈdrɔː/ and by producing a clear /ɔː/ vowel. Avoid turning it into ‘hydr-o-logic’ by linking the /dr/ cluster correctly: /ˈhaɪˌdrɔː.lɪks/. Practice the sequence hi-draw-liks with a single, smooth transition between consonants.
In US English, /ˌhaɪˈdrɔː.lɪks/ with strong rhoticity and a tense /ɔː/ in the stressed syllable. UK English often uses /ˌhaɪˈdrɔː.lɪks/ with similar rhoticity but subtle vowel length differences, and a slightly less pronounced /r/ in non-rhotic varieties; however, “hydraulics” remains rhotic in most UK speech. Australian English follows US-like rhoticity but may showcase a slightly more relaxed /ɔː/ and a more clipped second syllable.
Two main challenges: the /dr/ cluster after a high front diphthong and the long /ɔː/ in the stressed syllable, which can slide toward /ɒ/ for some speakers. The sequence hi-dru- with strong /dr/ and then a light final /lɪks/ can trip learners. Also, the “ru” portion blends quickly; keep the /r/ distinct before moving to /ɔː/. Consistent IPA-guided practice helps stabilize the rhythm and vowel quality.
A notable feature is the clear, stressed /drɔː/ portion after the initial /haɪ/. Learners often misplace the /r/ and shorten the vowel, but the correct pattern requires a full /ɔː/ in the stressed syllable and a smooth transition into /lɪks/. Visualize the flow: hi-draw-liks, with equal emphasis starting on the second syllable. IPA cues are essential for accuracy: /ˌhaɪˈdrɔː.lɪks/.

The word hydraulics comes from the Greek hydraulikos (water-sucking, water-working) from hydro- (water) + aition (action, orgin). Medieval Latin hydraulica and later English hydraulics borrowed from Greek, reflecting the foundational focus on water as the working fluid. Historically, the term broadened from a narrow study of water flow in pipes to the broader science of fluid power, encompassing liquids other than water in engineering contexts. Its emergence as a formal technical discipline aligns with 19th-century developments in fluid dynamics and the industrial demand for controllable liquid power, culminating in modern hydraulic motors and braking systems. First known usages appeared in Latin and Greek-derived scientific treatises and translated engineering texts, then popularized in the 1800s with the rise of industrial hydraulics and the adoption of hydraulic presses and cranes. The evolution mirrors broader advances in fluid mechanics, with the term evolving to describe both the study and application of liquid-based actuation across engineering domains.
