Oftentimes one can hear final l after a vowel get a vowel quality; whether this is an /u/ or /w/, I am not certain of. I have the feeling it is becoming more common today, but you can hear examples of this from earlier; in Pink Floyd’s The Wall for instance (‘Another Brick in the Wall Part II’), the children’s choir sings:
- 1′17″ ‘controw’ (‘control’)
- 1′55″ ‘wall’, though some of them say ‘waw’
- 2′04″ more ‘waw’ than ‘wall’?
My question then is twofold:
- How recent is this pronunciation of final -l following a vowel?
- Does this pronuncation indicate L is (or is becoming) a semivowel, as Y and W? If so, why / why not?
