Origins What is now English originated as the
Proto-Indo-European consonant *
kʷ (whose reflexes came to be written in
Latin and the
Romance languages). In the
Germanic languages, in accordance with
Grimm's Law, Indo-European
voiceless stops became voiceless
fricatives in most environments. Thus the
labialized velar stop *
kʷ initially became presumably a labialized velar
fricative *
xʷ in pre-Proto-Germanic, then probably becoming *
w̥ – a
voiceless labio-velar approximant – in
Proto-Germanic proper. The sound was used in
Gothic and represented by the letter
hwair. In
Old High German, it was written as , a spelling also used in
Old English along with (using the letter
wynn). In
Middle English the spelling was changed to (with the development of the letter w|) and then , but the pronunciation remained .
Developments before rounded vowels Before
rounded vowels, such as or , there was a tendency, beginning in the
Old English period, for the sound to become
labialized, causing it to sound like . Words with an established in that position came to be perceived (and spelt) as beginning with plain . This occurred with the interrogative word
how (Proto-Germanic *
hwō, Old English
hū). A similar process of labialization of before rounded vowels occurred in the
Middle English period, around the 15th century, in some dialects. Some words which historically began with came to be written (
whole,
whore). Later in many dialects was delabialized to in the same environment, regardless of whether the historic pronunciation was or (in some other dialects the labialized was reduced instead to , leading to such pronunciations as the traditional
Kentish for
home). This process affected the pronoun
who and its inflected forms. These had escaped the earlier reduction to because they had unrounded vowels in Old English, but by Middle English the vowel had become rounded, and so the of these words was now subject to delabialization: •
who – Old English
hwā, Modern English •
whom – Old English
hwǣm, Modern English •
whose – Old English
hwās, Modern English By contrast with
how, these words changed after their spelling with had become established, and thus continue to be written with like the other interrogative words
which,
what, etc. (which were not affected by the above changes since they had unrounded vowels – the vowel of
what became rounded at a later time). ==Wine–whine merger==
