u s e f u l and l o v e l y!
from Faulty Diction:
whack, what, which, etc
Pronounced hwac, hwat, hwich, etc.: not wac, wat, wich, etc.
The English are especially lax in the pronunciation of such words as these, almost uniformly dropping the initial h sound, while many Americans err by making the aspirate too sharply prominent.
