Post-w system: 


/w/, /u/, /k/, /g/ are articulated at the same location: velar, dorsal, high.


  /æ/ (no change): whack, wag (cf. rag, rack). This, because  w (k, g, u) and   /æ/ are not close.
  /æ/ --> /ɑ/  has, as, gas, rat, rash --> was, what, wash
  /u/ --> /ʊ/  food --> good
  /ɑ/ --> /ʊ/ golf -> wolf
  /ɑ/ --> /ɔ/ harm, card, car -> warm, warden, war (and pre-l system)
 /ɑ/ (no change): wobble, whopper, wok, wonky etc.
