schwu /ʃwuː/ noun1 •An indeterminate near-close central rounded vowel sound, such as the "u" in "awful" or the initial "o" in "omission", depending on the accent; sometimes represented as [[[ɵ]]] in IPA or [[[ᵿ]]] in para-IPA.Reflecting this loss of contrast, Wells uses schwi (the so-called ‘happy-vowel’) and schwu (weak-u), replacing [ɪ] and [ʊ] and giving [ˈhæpiə] and [ˈdʒæɡuə]. — 2011 formsschwus
