Adenovirus

Adenovirus is pronounced a-DEN-o-vi-rus with primary stress on the third syllable? Actually, standard stress is on the third syllable: a-den-O-vi-rus, but many say ADVancé? Let's provide precise: /ˌæ.dɪˈnoʊˌvaɪ.rəs/. In American pronunciation, you place stress on the 'no' or 'noʊ' as the primary? Your current IPA given is ˌæ.dɪˈnoʊˌvaɪ.rəs, which marks secondary stress on the first syllable and primary on the third? We should ensure: The word has four or five syllables: a-den-o-vi-rus. The common pattern: secondary stress on the first syllable and primary on the fourth? Actually IPA /ˌæ.dɪˈnoʊˌvaɪ.rəs/ shows secondary stress on first, primary on the fourth: æ-dɪ-NO-vai-rəs. So the answer should confirm: stress on 'noʊ' (the fourth syllable) with secondary on 'æ' (first). Provide mouth positions. Audio reference: mention you can listen on Pronounce or Cambridge audio.

Common errors: flattening the second syllable to mimic 'adeno' as 'ADD-eh-noh' rather than 'ad-eh-NOH'. Another error: placing primary stress on the first syllable or shifting to 'AD-uh-NOH-vi-rus'. Correct approach: keep the 'noʊ' as the strong beat and ensure the 'vi' is light but clear. Practice with slow syllables: æ-dɪ-NOʊ-və-rəs; use tongue tip behind lower teeth for 'd', rounded lips for 'oʊ', and crisp 'r'.

In US, US /ˌæ.dɪˈnoʊˌvaɪ.rəs/ tends to have rhotic 'r' clearly pronounced and a long 'o' in 'noʊ'. UK may reduce the second syllable slightly and maintain non-rhotic or weak rhotic 'r' depending on speaker; vowels may be tighter in 'noʊ' and 'vaɪ'. Australian tends toward broader vowel quality, with slightly reduced 'æ' and a more open 'ɒ' in 'no', but many pronounce similarly to US. Focus on rhotics and vowel length.

The difficulty lies in the multi-syllabic structure and the three consecutive vowel sounds 'ad-e-no' with a diphthong in 'noʊ' and 'vaɪ' that can be mis-timed. The secondary stress on the first syllable and the network of alveolar/dental sounds ('d', 'n') require precise tongue placement to avoid slurring. Practicing segmental accuracy with IPA helps you lock the rhythm and stress.

A practical tip: treat the word as four clear chunks: ad-eh-NO-vi-rus, with the stronger emphasis on NO (the third syllable). Keep the 'vi' light and avoid merging 'no' and 'vi' into a single sound. Use a slow tempo initially, then speed up while maintaining the same mouth shapes and breath flow, so the final -rus remains crisp.
