3 syllables: ae, ro, bic. Stress on ro.
er-OH-bik
/ɛˈɹoʊbɪk/
aerobic is pronounced er-OH-bik (/ɛˈɹoʊbɪk/). It has three syllables (ae-ro-bic), with the stress on "ro". Aerobic refers to processes or activities that require oxygen, especially those that sustain cardiovascular exercise and improve endurance. The term combines 'aero' (air) and 'biotic' (life), and is used to describe activities that support the body's use of oxygen over extended periods. In everyday use, it commonly describes exercise or fitness classes designed to elevate heart rate and respiration.

Pronounce as /ˌɛəˈroʊ.bɪk/ (US) or /ˌeəˈrəʊ.bɪk/ (UK). The primary stress falls on the second syllable. Start with two-diphthong vowel sounds in the first syllable, then a strong stressed /roʊ/ or /rəʊ/ before the final /bɪk/. Think: air-ROH-bick, with the second syllable carrying the main beat. Audio resources: consult Cambridge or Oxford dictionaries for audio clips.
Common errors: misplacing stress on the first syllable (AER-obic instead of a-e-RO-bic), and mispronouncing the second syllable as /roʊ-bik/ without the proper reduction of the first vowel to a schwa-like sound. Another frequent mistake is flattening the /ɪ/ in -bɪk to /iː/ as in ‘beek.’ Correction tips: keep the second syllable stressed, use a clear /roʊ/ or /rəʊ/ diphthong, and finalize with a short, clipped /bɪk/. Practice with minimal pairs: aero- vs a-RO- w.r.t. emphasis; // reference IPA: /ˌɛəˈroʊ.bɪk/ (US).
US: /ˌɛəˈroʊ.bɪk/ with rhoticity affecting the /r/ in /roʊ/. UK: /ˌeəˈrəʊ.bɪk/ with non-rhoticity often audible in post-vocalic /r/ weakening; /əʊ/ is common in /roʊ/. AU: /ˌeəˈrəʊ.bɪk/ similar to UK but with Australian vowel quality—more centralized and raised diphthongs for /eə/ and /əʊ/. Overall, vowel lengths are similar; rhotics are weaker in UK/AU than US. IPA references: US /ˌɛəˈroʊ.bɪk/, UK /ˌeəˈrəʊ.bɪk/, AU /ˌeəˈrəʊ.bɪk/.
Key challenges: diphthong transitions in /ɛə/ and /roʊ/ (US) or /rəʊ/ (UK/AU) require precise mouth shaping; the stress pattern shifts to the second syllable, which can feel counterintuitive if you expect aERO- to be stressed. The final /bɪk/ is short and clipped, so you must avoid adding a schwa before /bɪk/ and keep the vowel clarity. Practice with precision IPA cues: /ˌɛəˈroʊ.bɪk/ (US), /ˌeəˈrəʊ.bɪk/ (UK/AU).
A unique angle is the stability of stress: the primary stress lands on the syllable containing /roʊ/ or /rəʊ/, not on the initial or final; the initial syllable carries a weaker secondary stress. This helps distinguish aerobic from many multi-syllable fitness terms where prefix stress dominates. Focusing on the mid-syllable sonority and the clean, short terminal /bɪk/ will aid consistent pronunciation across contexts.

US: rhotic /r/ in /roʊ/ blends with a stronger American vowel quality; UK/AU: /r/ is less pronounced or non-rhotic, and /əʊ/ becomes a clearer, higher-back diphthong. Vowel shifts: /ɛə/ in US may sound more centralized; /eə/ in UK/AU may feel longer. IPA cues: US /ˌɛəˈroʊ.bɪk/, UK/AU /ˌeəˈrəʊ.bɪk/. Listen for the rounded lips on /roʊ/ and the crisp final /bɪk/.
Aerobic derives from the Greek roots aero- ‘air’ and bios ‘life,’ combined in late 19th to early 20th century scientific terminology. The prefix aero- is used broadly for air-related terms (aeronautics, aerosol). The suffix -bic is linked to -bios, indicating life or metabolism in biological contexts. The term gained prominence in physiology in the early 1900s as scientists described energy production in the presence of oxygen, distinguishing aerobic from anaerobic metabolism. Over time, it broadened to refer to exercise modalities that sustain oxygen consumption and to systems that rely on oxygen for energy (mitochondrial processes, aerobic respiration). The concept became central to sports science and fitness culture by mid-20th century, with popularization of “aerobic exercise” as a key training modality for improving cardiovascular health and endurance.
