One syllable: ous.
uhs
/əs/
ous is pronounced uhs (/əs/). It has one syllable (ous), with the stress on "ous". ous is a common English suffix forming adjectives and sometimes relating to nouns. It denotes a characteristic, quality, or state (e.g., gracious, numerous), and is typically unstressed in multisyllabic words. As a suffix, its pronunciation can influence the preceding vowel and consonant quality, making it a critical target for accurate reduction and linking in fluent speech.

- You may overemphasize the ending, making the final /s/ sound sharp instead of a soft, quick /s/. Keep the /ə/ light and brief. ocus on blending the stem last vowel into the suffix; avoid a hard boundary between them. - Misplacing stress on the suffix: stress tends to be in the stem, not on -ous, so you often hear /ˈdeɪɡərəs/ not /ˈdeɪɡərˌəs/. Practice locating the root-stress and letting -ous ride on the tail without forcing extra syllables. - Ignoring reduction: many -ous endings in longer words reduce the vowel. Train your ear to hear a light /ə/ or /ɪ/ before /s/, not a full vowel.

In most common English usage, -ous is pronounced as /əs/ or /əs/ with a schwa-like ending in unstressed contexts, especially in multisyllabic words. The last syllable in many -ous words is a short, reduced sound [əs], but in longer words the preceding syllable carries the primary stress. For instance, dangerous: /ˈdeɪɡərəs/, curious: /ˈkjʊəriəs/. When saturating a final syllable with 'ous' after a stressed stem, the ending tends toward a quiet /əs/. Mouth position: the tongue lightly closes near the alveolar ridge, lips relaxed, soft palate open, and the end is a short /s/ with a weak vowel preceding it.
Common errors include overemphasizing the schwa so the ending sounds like /ɒəs/ or /oʊəs/ instead of a quick /əs/. Another frequent mistake is treating -ous as a separate syllable with full vowel length, as in factor: mispronouncing as /ˈfæk-tɔr-əs/ instead of /ˈfæk.tə.rəs/. Additionally, learners sometimes fail to reduce preceding unstressed vowels, making the overall word sound exaggerated. Correction: practice the ending as a reduced /əs/ and blend it smoothly into the final consonant; practice fast, then slow down to feel the reduction.
Across accents, the main difference is how the final -ous sound is realized in a reduced vowel environment. US tends to maintain a slightly more rounded or schwa-like /ə/ before the final /s/ in less stressed contexts. UK and AU often produce a crisper, shorter schwa with less vowel coloring. Rhotic influences in US accents can affect the preceding vowel quality slightly (e.g., in dangerous, the /ər/ color). In many varieties, the -ous ending remains /əs/ in unstressed positions, but may be slightly longer in careful speech in non-American dialects.
The difficulty lies in the subtle vowel reduction and the quick transition from the main stem to the final /s/. In multisyllabic words, the -ous ending often gets reduced to a short /əs/ with minimal loudness, so you must manage coarticulation between the preceding consonants and the /ə/ before /s/. The challenge is maintaining the integrity of the stem vowel before the rapid /əs/ and keeping linking smooth without inserting extra vowels. Practicing with minimal pairs and listening for native pacing helps.
No standard '-ous' suffix in common English is silent. The sequence always contributes at least a /əs/ or /əs/ sound; however, in rapid speech the vowel can be reduced so that it sounds almost like a brief schwa before the /s/. In careful speech, you clearly hear /əs/ at the end, but in casual pronunciation, the vowel may be very short, reducing the auditory emphasis on the suffix.

- US: tends to maintain a fuller preceding vowel in stressed words; -ous remains /əs/ after a stressed root; rhotacized environments can color preceding vowels. IPA: /ˈdeɪɡərəs/ for dangerous. - UK/ AU: similar ending but with slightly crisper tensing before /s/ and less vowel color; non-rhotic tendencies may reduce linking. - Practice with words: curious /ˈkjʊəriəs/, dangerous /ˈdeɪdʒərəs/, numerous /ˈnjuːmərəs/, gracious /ˈɡreɪʃəs/; notice the final /əs/ sound and the reduced preceding vowel.
The suffix -ous comes from Latin -osus, meaning 'full of' or 'having the quality of,' deriving from the Latin -osus (full of) formed from the suffix -us with the adjectival suffix -osus. In English, -ous was adopted to heighten adjectives into descriptors of a quality or condition—gracious, laborious, dangerous—often indicating a state or property. The transition from Latin to English preserved the meaning while adapting to English stress patterns and morphology. The first known English uses align with late medieval to early modern periods as scholarly and literary writers adopted more Latinate vocabulary in technical and moral discourses. Over centuries, -ous became a productive, high-frequency suffix in everyday vocabulary, contributing to a broad spectrum of descriptors that articulate qualitative states, conditions, and affiliations. This evolution reflects broader trends in English towards Latinate morphology for precision and nuance in expression.
