Pronounced as /ruːl/. It’s a single stressed syllable with a long /uː/ vowel followed by the clear /l/ consonant. Start with a rounded, high back tongue position for /uː/, then transition to a light, alveolar or lateral /l/ with the tip or blade of the tongue touching the alveolar ridge. The jaw stays relatively closed, and there’s minimal vowel reduction. Audio references you can compare to include standard pronunciation in dictionaries and video tutorials.
Two frequent errors are shortening the vowel to a lax /u/ as in 'pull' and misplacing the tongue for the /l/—either a dark L with heavy retraction or a vowel-slash confusion. To correct: keep the tongue high and rounded for the /uː/ and avoid lowering the jaw prematurely; for the /l/, ensure the tongue tip contacts the alveolar ridge lightly while the blade supports the middle of the mouth, producing a clean light-to-neutral /l/ rather than a velarized or vowel-like ending.
In US/UK/AU, /ruːl/ remains rhotic in the US and AU, with a similar long /uː/ vowel; the key differences lie in vowel quality and possible length. UK RP might show a tighter front-of-mouth rounding and crisper /l/ lightness. Australian English typically features a centralized vowel quality and a slightly less defined L-sound in some regional varieties. Overall, the core rhyme stays the same, but the vowel height, rounding, and L-lightness can vary subtly by accent.
The challenge comes from maintaining the long /uː/ with a tight lip rounding while transitioning to a light alveolar /l/ at the end, which can easily tilt toward a diphthong or a dark L in some accents. The minimal articulatory adjustments—keeping tongue high, rounding lips, then a clean, unobstructed L release—demand precise control of lip tension and tongue blade position to avoid vowel reduction or a bloated final consonant.
Rule features a compact, single-syllable structure with a long high back vowel followed by a light L. This makes it a classic example of a tense, closed syllable where vowel length is crucial and final consonant clarity (L) determines the word’s crispness. The unique focus is sustaining the /uː/ quality through the /l/ without letting it drift into a schwa or vowel shortening, which is a common pitfall in rapid speech.

Rule derives from the Old French recuil or regul, stemming from Latin regulus meaning a guide or rule, and from regula meaning a straight stick or rule used for measuring. The sense evolution moves from a physical measuring device to an abstract standard by the Late Middle Ages. In English, early uses describe a measuring rule or standard and later broadened to governance, commands, and principles. The term appears in Middle English as reule or rule, gradually aligning with the sense of established commands or laws. The development reflects a long history of authoritative norms, from legal and ecclesiastical contexts to everyday procedures, forming the modern concept of a principle or directive that governs behavior or procedure. First known uses appear in legal and scholastic Latin-to-French-to-English borrowings during the 14th–15th centuries, expanding to general governance in subsequent centuries. The word’s semantic range now spans formal laws to informal conventions and even mathematical or computational rules. (Approximately 230 words)
