You say ZEE-roh with primary stress on the first syllable. In US/UK you’ll hear /ˈziːroʊ/ or /ˈzɪəroʊ/ depending on how the speaker treats the second vowel. Start with a clear, tense /z/ then an extended /iː/ (or /ɪə/) vowel, followed by a relaxed /roʊ/ or /rəʊ/. Visual: lips spread for the /iː/ and slight rounding for /oʊ/. IPA: US /ˈziːroʊ/, UK /ˈzɪərəʊ/, AU /ˈzɪəɹoʊ/.
Common errors: (1) Underpronouncing the second syllable, making it too quick so it sounds like one syllable; (2) treating the first vowel as a short /ɪ/ instead of the longer /iː/ in American speech; (3) dropping the final /oʊ/ by ending with a clipped /o/ or /əʊ/. Correction: elongate the first vowel to /iː/ (or /ɪə/ in some accents) and clearly glide into /roʊ/ or /rəʊ/, shaping lips from spread to rounded for the diphthong.
In US English you’ll likely hear /ˈziːroʊ/ with a long /iː/ and full /roʊ/. UK English tends to reduce the first vowel to /ɪ/ or a short /ɪə/ and a clearer /əʊ/ → /ˈzɪərəʊ/. Australian often sits between them with /ˈzɪəɹoʊ/ or /ˈzɪərəʊ/, with less rhoticity than US but more than some UK styles. Rhoticity affects whether the /r/ is pronounced before vowels in connected speech; in non-rhotic UK varieties, the /r/ at the end may be silent or weakened, affecting the /roʊ/ portion.
Two main challenges: (1) the diphthong in the second syllable; many learners flatten /roʊ/ to /ro/ or mispronounce as /oʊ/. (2) Vowel length and quality in the first syllable varies by accent; learners may misjudge /iː/ vs /ɪɪ/ or /ɪə/ depending on their native language. Also, the subtle difference between /ˈziːroʊ/ and /ˈzɪəroʊ/ requires careful lip rounding and tongue height awareness in the second syllable.
Zero has a strong first-syllable emphasis with a clear onset /z/ and a trailing, rounded second syllable vowel that carries the /roʊ/ or /rəʊ/ diphthong. The second vowel is often reduced or altered in casual speech, so you’ll hear /ˈziːroʊ/ in American speech and /ˈzɪərəʊ/ in British speech. Pay attention to the transition from /iː/ or /ɪə/ into the /roʊ/ vowel and keep the /r/ crisp in rhotic accents.

The word zero originates from the Italian zero, which itself comes from the Arabic sifr meaning ‘empty’ or ‘vacancy.’ The concept entered medieval Latin as zephyrus? No—that’s a different root. In mathematics, the symbol and the concept were popularized through translations of Indian and Arabic treatises on arithmetic; the numeral 0 was first documented in ancient India (the Bakhshali manuscript and later works) and was transmitted to the Islamic world where sifr was used and later Latinized as cifra or zephir. By the time of the European Renaissance, zero had become a crucial placeholder in positional numeral systems, enabling the development of advanced algebra and calculus. The modern English form zero entered via Old French zere, or from Latin zeorum/zeorum? The exact pathways vary by language, but by the 16th century the term zero was established in mathematical discourse in English and soon became common in science, computing, and everyday use, marking its transformation from a abstract mathematical concept to a concrete reference for quantity, absence, and starting points.
