/ˌlɪkwəˈfækʃən/
Liquefaction is pronounced lik-wuh-FAK-shuhn (/ˌlɪkwəˈfækʃən/). It has four syllables (Li-que-fac-tion), with the stress on "fac". Liquefaction is the process of turning a substance, typically a gas, into a liquid or the transformation of a solid into a liquid-like state under pressure or temperature conditions. In geology, it refers to the temporary loss of strength and stiffness of saturated soil due to earthquake-induced shaking. The term is commonly used in engineering, environmental science, and natural disaster contexts.

"The liquefaction of natural gas requires cooling to extremely low temperatures to become a usable liquid fuel."
"During the earthquake, soil liquefaction caused buildings to settle unevenly and topple."
"Engineers study liquefaction risks to design foundations that remain stable during seismic events."
Pronounce as li-QUÉ-fac-tion with primary stress on the third syllable: lɪ-kwɛ-ˈfæk-ʃən in US notation; UK typically li-kwɪ-ˈfæk-sɪən with secondary stress near the end. Break it into four syllables: li-que-fac-tion, focus on the /ˈfæk/ syllable as the peak. Overall: lɪ-ˌkwɛ-fæk-ʃən or lɪ-kwɪ-ˈfæk-sjən depending on the accent.
Common mistakes include misplacing stress (treating it as li-QUE-fac-tion) and slurring the -faction into -fiction. Another error is pronouncing /kw/ as separate sounds in quick speech (e.g., lɪ-k-wɛ-fæk-ʃən). Correct by emphasizing the /kw/ as a unit after the initial /l/ and reducing the schwa to clear /ɪ/ in the first syllable. Practice the sequence li-kwə-FAK-shən with IPA guidance.
In US English you’ll hear lɪˌkwɛfˈæk.ʃən with strong /ɛ/ in the second syllable and a clear /æ/ in the third. UK English often has a slightly shorter first vowel and a palatalized quality on the -faction syllable, rendering lɪkwɪˈfæk.sɪən. Australian often reduces the first vowel slightly to /ɪ/ or /ɪə/ and may have a less rhotic r-influence, producing lɪkwəˈfæʃn̩. Focus on the /kw/ cluster as a single unit in all accents.
The difficulty lies in balancing the consonant cluster /kw/ after a stressed syllable and the successive /ʃ/ sound in -tion. The surface rhythm moves quickly from /kw/ into /æ/ and then /ʃən/. Additionally, the second and third syllables carry the main stress, which can lead to misplacement if you expect the stress on the first syllable. Practice the four-syllable rhythm with careful /kw/ articulation.
Notice the delicate boundary between the root liqu- and the suffix -faction. The /kw/ immediately precedes /ɛ/ or /ɪ/ depending on accent, so avoid turning it into 'liq-uh-FAK-shn' by clearly gliding from /kw/ into the stressed /æ/ or /ɪə/ and then the /ʃən/ ending. Mouth shapes should move smoothly from a rounded lip position for /w/ to a tense bilabial /p/‑like /f/ control into /æ/ and /ʃ/.

Liquefaction comes from the Latin word liquefacere, meaning to liquidify or dissolve. The root liq- derives from liquidus (fluid, liquid) and facere (to make, to do). The English noun liquefaction first appeared in the scientific lexicon during the 19th century, when thermodynamics and phase-change studies proliferated. Initially used to describe the conversion of gases to liquids (gas liquefaction) and the condensation of vapors under pressure, the term broadened to geology and civil engineering to describe soil behavior under seismic loading. By the mid-20th century, liquefaction was central to earthquake engineering and groundwater hydrology, highlighting the process's importance in predicting structural stability, fluid behavior in porous media, and the handling of cryogenic liquids in industrial settings.
