The 'k' in Knee and Light opus 968

There is a linguistic story about the 'k' in 'knee' and 'light'!
They are 'linguistic fossils' from when English speakers
Pronounced every letter.
'K' is visible in knee, but hidden inside the'gh' of light.
These words show how English sounded long ago.
In Old and Middle English 'kn' was entirely spoken as in 'k-nee'.
The 'k' sound requires air to be pushed from the back of the throat,
Followed by 'n', using the front of the tongue.
Speakers streamlined their speech; this process is called 'apheaesis'.
By the 16th and 17th centuries the awkward 'k' was dropped.
But in modern German, knee (nee) is Knie (k-nee)!
In 'light,' there is a hidden fossil.
Historically, the 'gh' spelling represents a guttural, scratchy 'k-like' sound.
The linguists call this a velar fricative.
In German, Licht (light) or the Scottish word loch, has a throat-clearing 'ch'.
In Old English, light was spelled leoht and sounded like the German Licht.
Norman French scribes took over English record-keeping after 1066.
French had no throat sound like 'ch,' so scribes began using 'gh' to spell it.
Eventually, English speakers stopped using the harsh throat sound.
Words like light, night, and thought lost the 'ch' sound,
And lengthened the vowel before it.
Also, with other words like rough and tough,
The sound changed into an 'f' sound.
The sounds disappeared, but the spelling remained the same.
This was thanks to William Caxton
And the English printing press in the late 1400s,
Where standardized English spelling was based on how
Words were pronounced at that exact time.
Soon after, massive shifts occurred in the spoken language,
But so many books had been printed
That spellings became frozen in time.
