You pronounce it as /wʌns/. The initial /w/ is a bilabial-velar approximant with light lip rounding. The stressed syllable is monosyllabic here, so the vowel is a short, lax /ʌ/ like ‘strut,’ and the final /ns/ is a nasal plus voiceless alveolar fricative. In connected speech, you’ll often hear a swift, clipped release: wuhns. IPA: /wʌns/; mouth: lips lightly rounded, tongue relaxed mid-low, jaw slightly dropped.
Common errors include elongating the vowel as in ‘onees’ or misplacing the /n/ and /s/ into a single consonant cluster. Some learners tense the jaw or over-enunciate the /ʌ/, producing an overly bright vowel like /ɒ/. To correct: keep the vowel short and lax (like /ʌ/ in ‘strut’), maintain a clean alveolar nasal /n/ touch, and release into /s/ without blending the two into a single sound. Focus on a crisp /ns/ sequence rather than a drawn-out ‘on-s.’
In General American, you’ll hear a short /ʌ/ and a quick /ns/; the /w/ is a light onset. In British English, /ʌ/ remains short, with slightly crisper consonants and less vowel reduction in careful speech. Australian English tends to have a centralized or slightly higher /ʌ/ and a softer /s/ due to accent-specific vowel timing; some speakers may vowel-shift toward /ɒ/ in casual speech. Across all, the word remains a monosyllable with a strong final /ns/ cluster.
The challenge lies in the tight /ns/ coda cluster and the short, lax vowel /ʌ/. Many learners mispronounce by adding extraneous vowel length, or by turning /w/ into a full-voiced onset that blends with the vowel. Mastery requires crisp onset /w/, a compact /ʌ/ vowel, and a clean /ns/ sequence without voicing changes. Practicing with minimal pairs and controlled pace helps farm-tresh punctuation of the sounds.
A unique nuance is the way the initial /w/ can be lightly vocalized or even slightly devoiced in fast speech, which makes the onset feel almost like a glide transitioning directly into the /ʌ/ vowel. Some speakers also reduce the vowel a touch in rapid casual speech. Paying attention to a crisp, brief /w/ onset and a non-elongated /ʌ/ helps anchor the word in rapid dialogue.

The word once comes from Old English ǣne, oncen, or ǣfne, with roots in the Proto-Germanic word *ainiz meaning ‘one, single.’ In Middle English, once evolved to signal a single time or event, derived from the sense of ‘one time’ or ‘a single occasion.’ The particle usage expanded to temporal phrases like ‘at one time’ and later to mean ‘formerly’ or ‘formerly, in the past.’ The spelling stabilized as once in Early Modern English, and its semantic range broadened to include immediate succession or repetition (as in ‘once more’) as well as emphasis in commands and storytelling. First known written use appears in Old English and early Middle English texts, with common attestations in law, poetry, and prose as a marker of a singular occurrence or past moment.
