Have you ever really thought about now and know
Like the letter k changes the sound of o how does that even work wtf
Did someone say historical linguistics? No? Too bad!
Now is a descendant of the Old English word nū, while know comes froms the O.E. cnāwan. The former developed into now, nou, and nu in Middle English, and the latter became knowen. As a side note, there are frequently multiple spellings for Middle English words because the orthography wasn’t yet standardized to a West Midlands pronunciation yet.
Later still, there was this epic set of sound changes that would be retroactively named The Great Vowel Shift. So named because it was happening for about five centuries, from the 1400s to the 1900s.
The Great Vowel Shift is responsible for turning the /u:/ sound of now, nou, and nu into the /aʊ/ that we’re familiar with today. Through the centuries, the /ɔu/ of knowen changed into the /əʊ/ and /oʊ/ of British and American English, respectively.
Reblogging again because Alex just explained all of this in the most awesome of manners.
