Fault is a single-syllable word pronounced with the /fɔlt/ sound in US English and /fɔːlt/ in UK/Australian English. Start with an /f/ friction at the lips, move into a rounded open-mid back vowel /ɔː/ (US /ɔ/), then close with a clear /l/ and a final /t/. The main tip: keep the vowel longish and avoid turning it into /ælt/ or /oʊlt/. Hear it as 'fawlt' with a crisp /t/ release. IPA: US /fɔlt/, UK /fɔːlt/, AU /fɔːlt/.
Two common errors: first, shortening the vowel to /æ/ as in 'cat' or broadening to /oʊ/—neither matches the /ɔː/ (US /ɔ/, UK/AU /ɔː/). second, losing the final /t/ or injecting an extra vowel between /l/ and /t/. Correction: maintain a single, steady /ɔː/ (US /ɔ/) before the /l/ and finalize with a crisp /t/. Practice with minimal pair: /fɔlt/ vs /fælt/ and /foult/ to feel the difference.
In US English, /fɔlt/ with a rhotacized vowel sometimes near /fɑlt/ depending on regional dialect, but most regions keep /ɔ/. UK/AU use /fɔːlt/ with a longer, pure /ɔː/ and non-rhoticity sometimes yielding a slightly vowel-lengthened quality. The /t/ is typically a clear alveolar stop in all. The main differences are vowel length and quality: US may have a shorter /ɔ/ in some dialects; UK/AU preserve a fuller /ɔː/. For rhotics, US speakers often pronounce the /r/ not relevant here since fault is non-rhotic; still, some US dialects show subtle merging with /ɒ/ in certain regions.
The challenge lies in the mid-back rounded vowel /ɔː/ (US /ɔ/), which is easily misheard as /ɑ/ or /æ/ by non-native speakers. The sequence f- + rounded vowel + l + t requires precise lip rounding shifting to a neutral or spread lip posture for the /l/ and final alveolar stop. The clear, unreleased or aspirated /t/ can also vary by dialect, adding pronunciation ambiguity in fast speech.
Focus on keeping your mouth rounded for /ɔː/ and then switch quickly to a light, precise /l/ articulation; avoid an intrusive extra vowel between /l/ and /t/. A quick visual cue: imagine the lips rounding for /ɔː/ and then relax into a tight tip-to-alveolar touch at /t/ without voicing after release.

Fault comes from the Old French faut, from Latin fallere meaning 'to deceive' or 'to err', but in English it evolved from the sense of 'a misdeed or fault' and later 'a defect or crack'. The semantic shift widened through Middle English usage, where fault referred to blame or responsibility, and to geological fault lines by the 17th–18th centuries as scholars described fractures in rocks. The modern sense includes mechanical defects and errors in systems, enabling phrases like 'at fault' or 'fault in the system.' The pronunciation and spelling stabilized in Early Modern English, with the root connected to Latin fallere via French faut, retaining the final -t sound in many dialects. First known uses appear in legal and theological texts of medieval Europe, where culpability and fault lines were metaphorically extended to natural and man-made flaws. Through the Industrial Revolution, fault became common in engineering discourse, highlighting defects in machinery, materials, and infrastructure. The word’s broad applicability now spans geology, engineering, law, psychology, and everyday talk about mistakes or defects.
