2 syllables: deaf, ness. Stress on deaf.
DEF-nuhs
/ˈdɛfnəs/
deafness is pronounced DEF-nuhs (/ˈdɛfnəs/). It has two syllables (deaf-ness), with the stress on "deaf". Deafness is the condition of partial or total inability to hear in one or both ears. It encompasses a spectrum from mild hearing loss to profound deafness and may involve fluctuating or permanent impairment. The term is commonly used in medical, audiological, and everyday contexts to describe reduced auditory perception and its impact on communication and daily life.

- You might over-articulate the /f/ by adding lip rounding or a prolonged release; instead, keep a relaxed /f/ with a crisp, short breath and quick transition to /n/. - Another error: inserting an extra vowel between /f/ and /n/ (e.g., /ˈdɛf.ɪ.nəs/); aim for a seamless /f.n/ transition by practicing with a light pause and strong contact between /f/ and /n/. - Finally, people often inglesibly pronounce as /ˈdiː.fnəs/; keep the first syllable short, not a long /iː/; ensure the vowel is lax as in ‘bet’. Practice with tongue placement in isolation and in connected speech.
"Her deafness makes it difficult for her to follow conversations in noisy rooms."
"The clinic offers hearing aids and therapies to help manage deafness."
"She was diagnosed with deafness after a routine test, prompting early intervention."
You say /ˈdɛf.nəs/. The primary stress is on the first syllable: DEF-nəs. Start with a clear 'd' touch, then the short 'e' as in 'bed', then 'f' and a light, unstressed second syllable with a schwa-like 'ə' before the final 's'. Mouth positions: tip of the tongue near the alveolar ridge for /d/, upper teeth lightly touching lower lip for /f/, and a relaxed, central vowel for /nəs/. Listen along with a native pronunciation to reinforce the rhythm.
Two common errors are misplacing the stress (uttering /ˈdiːf.nəs/ with a long E) and turning the final /s/ into a z-sound (/ˈdɛf.nəz/). Corrective tips: keep the first syllable stressed and short, as /ˈdɛf/. For the final syllable, end with a crisp /s/ rather than a voiced /z/; practice by holding a crisp air release after the /n/ and before /s/. Ensure the /f/ is a voiceless fractal fricative, not a bilabial or labiodental substitute.
In US and UK, the initial /d/ is alveolar with a quick release; /ɛ/ is a lax front vowel; /f/ is a voiceless labiodental fricative; final /nəs/ is a nasal followed by a schwa and /s/. Some regional US speakers reduce /ə/ in the second syllable, making it closer to /dəfˈnəs/ in fast speech. In Australian English, you may hear a slightly wider vowel quality on /ɛ/, and the final /n/ may be more nasalized; overall rhoticity is variable, but /ˈdɛf.nəs/ remains common. IPA references: US /ˈdɛf.nəs/, UK /ˈdɛf.nəs/, AU /ˈdɛf.nəs/.
The main challenge is the clustered consonants around /f/ and /n/ and maintaining a clean final /s/ in fluent speech. Lip control for /f/ (lower lip against upper teeth) must be precise while releasing into the alveolar /n/ without inserting an extra vowel. The transition from /f/ to /n/ requires keeping the mouth closed for a moment to avoid a fused /fn/ sequence. Finally, keeping the second syllable unstressed expects a quick, quiet schwa before /s/—a subtle, fast syllable.
There are no silent letters in deafness, but the primary stress is on the first syllable. The second syllable is weak and unstressed, containing a schwa-like vowel before the final /s/. The key is timely release: /ˈdɛf.nəs/ with a short, crisp /n/ before the unstressed /əs/. Mis-stressing the second syllable is a common search-query concern, so focus on keeping the first syllable prominent and the second quick and light.

- US: keep r-less, vowel laxity; /ɛ/ is mid-open front; stress on first syllable; final /əs/ reduces to /əs/ with a light, clipped /s/. - UK: similar pattern, but some speakers may exceed vowel length slightly; avoid over-aspiration on /d/; maintain alveolar tap followed by /f/. - AU: often broader vowel in /ɛ/, more nasalized final /nəs/; keep /d/ clearly released; non-rhotic tendencies affect the liquid quality in connected speech.
The word deafness derives from Old English deaf, meaning unable to hear, which itself traces to Proto-Germanic *daubaz (related to unable, dull) and Proto-Indo-European root *dwe- meaning? The modern sense of ‘deaf’ as lacking hearing emerges in early medieval English, with -ness forming a noun indicating a state or condition. Historically, ‘deaf’ as a personality or moral sense also existed (e.g., dulling of senses). By the 16th–18th centuries, deafness was used in medical texts to denote a persistent impairment of auditory perception, separating the condition from temporary or fluctuating hearing loss. The term evolved alongside advances in audiology, with shorthand usage in clinical notes and patient communication. First known written attestations appear in medical glossaries and anatomy treatises of late medieval England, and by the 19th century, deafness became a standard clinical and social descriptor in many European languages, with equivalents in French (surdité), German (Taubheit), and Spanish (sordera).
