who pronounces an h at the beginning of words such as white

The whine-wine merger (link) is one of many interesting phonological changes to have occurred to English over the past millennium or so. I take it you are from somewhere in the NE of the USA. (I see the Vermont on your profile, but you could've moved.) Some wh do not go back to Old English hw (early PIE *kw-), such as whole (< OE hāl). How about some of the wh-word that lost their labelization early on, such as who? I assume your dialect hasn't gone through the cot-caught or Mary-merry-marry mergers yet either ...

Ceci n'est pas un seing.
