nonunion is pronounced nah-NYOO-nyuhn (/nɑˈnjunjən/). Nonunion refers to the failure of two or more bone fragments to heal and join after a fracture, or a failure of a fracture to progress through the normal healing stages. It describes a medical condition where the bone ends remain unconnected for an extended period, potentially requiring intervention. The term is used in orthopedics and radiology to indicate incomplete or absent bone union.

Say /ˌnɒnˈjuːniən/ in UK English or /ˌnɑːnˈjuːnjən/ in US English. The primary stress is on the second syllable 'ju-'; the 'non-' prefix is unstressed, often reduced. The vowels are distinct: 'non' with a short o, and 'union' starting with 'ju' as in 'you' and ending with 'ən' (schwa). Pronounce the final 'ion' as '-iən'.
Common errors include misplacing the stress (trying to stress 'non' rather than 'ju'), mispronouncing the 'ju' as 'you-n' or 'unit' endings, and slurring the final '-ion' into a clear 'ən' instead of a clean 'ən'. Correct by emphasizing the 'JU' syllable: non- JU - ni - on, ensuring the 'ju' sounds like 'you' and the final '-on' uses a light schwa followed by an 'n' sound.
In US English, the secondary stress pattern yields /ˌnɒnˈjuːniən/ with a strong 'juː' and a reduced final syllable. UK English tends to a shorter 'o' in the first syllable and a slightly clearer final '-ən', /ˌnɒnˈjuːniən/. Australian English aligns with nonrhotic tendencies but maintains the same syllable sequence, with a similar '/ˌnɒnˈjuːniən/' realization; vowel qualities can shift slightly, but the JU-n portion remains prominent.
Two main challenges: the tri-syllabic rhythm with primary stress on the second syllable and the 'ju' cluster (/ˈdʒuː/ or /juː/). The combination of a short first syllable, a stressed 'ju' vowel, and a trailing 'ən' can cause listeners to misplace stress or merge syllables. Focus on clear separation: non- JU - ni - on, keeping the 'ju' sound as 'you' and the final schwa distinct.
While related forms exist, 'nonunion' preserves the simple -ion ending as 'iən' and places primary stress on the 'ju' syllable. Forms like 'nonunioned' introduce a 'ed' ending and can shift rhythm and vowel length. In general, keep the 4-syllable pattern with primary stress on the second syllable and avoid adding extra vowel through over-enunciation.

The term nonunion comes from Latin non- meaning 'not' and union from Latin unio, unity or joining, with the suffix -ion forming a noun denoting the state or condition. The concept in medicine arose in the late 19th to early 20th centuries as radiography allowed clearer assessment of fracture healing. Early orthopedic texts described fractures that failed to consolidate, using phrases like 'non-union' to denote the absence of bony union. Over time, the term broadened to include cases where the fracture shows no progression toward healing despite appropriate intervention, and it has since become a standard clinical descriptor across radiology and orthopedics. The hyphen was commonly used historically (non-union) but modern usage often drops it to nonunion in clinical notes, prescriptions, and research titles. First known uses in medical literature appear in case reports from Europe in the late 1800s, aligning with the period of advancing surgical and imaging techniques that clarified healing processes and their failures.
