Pronounce as /nɒb/ in British English or /nɑːb/ in American informal speech depending on region, with a silent K. The mouth starts with a light /n/ tongue contact, followed by a short, rounded vowel, and a final voiced /b/. In careful speech you may lengthen the vowel slightly to around /nɒːb/; in American casual speech you’ll often hear /nɑːb/ or /nɒb/ depending on dialect. IPA: US /nɑb/, UK /nɒb/, AU /nɔːb/.
Common errors: pronouncing the initial /kn/ cluster as /kn/ with audible K or as /n/ only; not voicing the final /b/ or letting it sound like /p/. To correct: drop the K entirely after the nasal onset (start with /n/), ensure the vowel is short and rounded, and finish with a clear voiced /b/ without aspiration. Practice with minimal pairs like knob vs nab to emphasize the /b/ ending.
In US English, knob is typically /nɑːb/ or /nɑb/ with a long or lax low back vowel; the /r/ is absent (non-rhotic in many dialects). In UK English, /nɒb/ with a shorter, more rounded /ɒ/ vowel and a glottalization less common but possible in rapid speech. Australian /nɔːb/ sits between US and UK, with a broad /ɔː/ or /ɔ/ quality and a non-rhotic tendency. The initial /kn/ becomes /n/ with K being silent in all. For all, the final /b/ remains voiced and stable.
The challenge lies in the silent K cluster at the start and the rapid transition from /n/ to a rounded short vowel before /b/. Speakers often over-articulate the /k/ or mispronounce the vowel length, leading to /nkb/ or /nəb/ errors. Proper articulation requires keeping the tongue at the alveolar ridge for /n/, then quickly rounding the lips for /ɒ/ or /ɑː/ before voicing /b/. Consistent, relaxed jaw posture helps clarity across dialects.
In word-initial clusters, you sometimes hear speakers trying to articulate the silent letter; focus on a clean /n/ onset and a short, rounded vowel, then a crisp /b/. The stress is on the single-syllable word anyway, so there is no extra syllable or stress pattern to manage. The key is precise mouth positions: tip of the tongue to alveolar ridge for /n/, rounded lips for /ɒ/ or /ɑː/, and closed vocal cords for /b/. IPA: /nɒb/ or /nɑb/.

Knob traces to Middle English nobe/knobbe from Old Norse knappr, with related Germanic forms. The term originally described a rounded lump or protuberance and for objects shaped like a small mound. Its earliest senses referred to a rounded projection on a weapon or tool, evolving to denote any protrusive button-like part on furniture or mechanisms. In the 16th–17th centuries, knob gained frequent domestic usage as a handle for doors, chests, and utensils. The sense extended to mechanical controls (e.g., volume knobs) as devices incorporated turning motions. Over time, knob also served metaphorically to describe rounded lumps in geography, anatomy, or abstract constructs, though the primary domain today remains physical handles and controls. First known written use appears in medieval English texts, with regional variants in Norse- and Germanic-influenced dialects, solidifying its use in household and hardware lexicon by the early modern period.
