Pronounce as un-TAI-ring, with primary stress on the second syllable: /ʌnˈtaɪərɪŋ/ in US and UK. The middle diphthong is /aɪ/ as in bite, followed by a light schwa before the final /ɪŋ/. If you’re thinking in syllables: un-TAIR-ing. In careful speech you’ll clearly articulate the /ˈaɪə/ sequence for a crisp middle, then finish with the /r/ (US/UK differ in rhoticity, see accent notes). Audio references: consult dictionaries with IPA audio or Forvo samples for native pronunciation.
Two frequent errors: (1) stressing the first syllable instead of the second, which smooths the word into un-TIR-ing; practice placing the primary beat on /taɪ/ and keeping /t/ clearly enunciated. (2) Mispronouncing the /aɪə/ as a simple /aɪ/ or swallowing the /ə/; ensure the sequence /aɪər/ is heard briefly before the final /ɪŋ/. Use minimal pairs and exaggerate the /ɪŋ/ closure in practice to fix. Regular listening helps embed the two-syllable rhythm.
US: rhotic /r/ present; /ˈtaɪər/ homeland closer to /ˈtaɪɚ/ for some speakers, with a pronounced /r/ before the final /ɪŋ/. UK: non-rhotic typically, the /r/ is not pronounced in coda; /ˈtaɪə.rɪŋ/ may surface as /ˈtaɪə.rɪŋ/ between vowels, with weaker r-coloring. Australia: rhotic but with a flatter /ɜː/ or /ə/ in unstressed syllables; the /aɪə/ sequence may be slightly longer and less pharyngealized than US. Overall, the nucleus /aɪə/ bridging into /r/ or /ɹ/ significantly influences perceived vowel quality and rhythm across dialects.
The difficulty lies in the two adjacent vowel sounds /aɪ/ and /ə/ within a short span, creating a slight diphthong sequence that can blur in fast speech. The /r/ is articulated differently across accents, affecting syllable weight. Additionally, keeping the mid syllable unstressed while delivering a clear /taɪ/ and final /ɪŋ/ challenges many non-native speakers. Practicing with controlled tempo and silent-mouth mirroring helps master the precise movement.
A word-specific nuance is the embedded /t/ after a vowel cluster; some speakers insert a light alveolar stop between /n/ and /t/ in fast speech (un-ten-tiring) which is an unwanted epenthesis. The clean form is /ʌnˈtaɪərɪŋ/ with seamless transition from /n/ to /t/; maintain a crisp /n/ then immediately release into /t/ without extra vowel. This keeps the rhythm tight and the stress on the second syllable.

Untiring combines the prefix un- (indicating negation or absence) with tiring (present participle of tire, from Old French tifir, from Latin later related to ‘to tire, fatigue’). The root idea is literally ‘not tiring.’ The compound formation follows a long tradition in English of creating adjectives by negating a present participle to convey continuous or perpetual action. Tiring itself appears in Middle English, with roots tracing to Latin torpēre or French raraire in related senses of fatigue; the modern sense of “not easily tiring” crystallized in English by the 17th–18th centuries as speakers described persistent exertion or endurance. The word gained traction in moral and practical discourse during the Industrial and Victorian eras, when commentators praised workers and reformers for their indefatigable spirit. Over time, untiring has remained a formal to semi-formal descriptor, often used in political rhetoric, biographies, and progress-oriented writing to convey admirable persistence without fatigue. In contemporary usage, untiring emphasizes resilience and continuous effort in service of a goal, rather than mere duration of activity.
