Voiceless bilabial plosive to Close back rounded vowel
The shift from the bilabial stop [p] to the high-back rounded vowel [u] is a form of vocalization. It typically occurs in syllable codas, where the labial stop weakens into a glide [w] and merges with the vocalic nucleus. This is a defining historical feature of the Portuguese language.
