Regarding the whine/wine merger but without getting too fussy about details and history nor trying to be hypercorrect, am I wrong if I use the unvoiced w (whispered h) before words like:
what
when
whine
whale
Some people use the whispered "wh" and some use the voiced "w". I personally find that a very obvious whispered "wh" sounds somewhat old-fashioned, verging on pretentious.
Also, not exactly related, can you show me some words where the h is silent in English, like:
hour
honest
honor
heir
herb
Try Googling for more lists of words starting with a silent "h".
Note: in BrE, we always pronounce the "h" at the beginning of "herb". In AmE, it sounds like "erb".
