The evolution of a CDK resource...
Lots of you will recognise this little story behind the names of UPPERCASE and lowercase letters. ๐
It's one of my favourite pieces of language history, and my students always love discovering where those names came from.
Originally, this resource was going to include two word matrices: one for and one for . Because ๐๐๐๐๐ก๐๐๐ ๐๐๐๐ ๐ is written as two separate words, the plan wasn't to include both bases on the same matrix.
But then the research began...and one little discovery led to the next.
My first stop was the Oxford English Dictionary (which I can access FREE online through my local library with my library card - definitely check to see if you can do the same ๐ฅณ). It was there that I noticed the OED analyses ๐๐๐๐๐ก๐๐๐ ๐๐๐๐ ๐ as a compound.
As I dug a little deeper, I discovered that ๐๐๐๐๐ก๐๐๐ ๐๐๐๐ ๐ was once a hyphenated compound before becoming the open compound we use today.
Since I already include both bases in my matrices for closed compounds (e.g. ๐๐๐๐ก๐๐๐๐), hyphenated compounds (e.g. ๐ค๐๐๐-๐๐๐๐ค๐) and connected compounds (e.g. ๐๐ข๐ก๐๐๐๐๐โ, where the bases are joined by a connecting vowel letter), it suddenly made sense to include both bases here as well, even though ๐๐๐๐๐ก๐๐๐ ๐๐๐๐ ๐ is written as two separate words.
By now, the resource was taking me somewhere I hadn't expected.
Then I started wondering: if the compounding of ๐๐๐๐๐ก๐๐๐ ๐๐๐๐ ๐ had changed over time, what about ๐ข๐๐๐๐๐๐๐ ๐ and ๐๐๐ค๐๐๐๐๐ ๐?
Naturally, that sent me back to the OED...
Sure enough, they have their own fascinating history, too. They began as ๐ข๐๐๐๐ ๐๐๐ ๐ and ๐๐๐ค๐๐ ๐๐๐ ๐, later became ๐ข๐๐๐๐-๐๐๐ ๐ and ๐๐๐ค๐๐-๐๐๐ ๐, and eventually settled into the closed compounds ๐ข๐๐๐๐๐๐๐ ๐ and ๐๐๐ค๐๐๐๐๐ ๐ we most often use now.
Then came my favourite discovery...
While checking the denotations for ๐๐๐๐๐ก and ๐๐๐๐ ๐ , I discovered that they both ultimately trace back to the same Latin root, ๐๐๐๐๐๐๐. ๐ฒ
That discovery sent me straight back into the research.
I checked Etymonline, went back to the OED, and cross-checked other sources.
And yes...every source led back to ๐๐๐๐๐๐๐.
Suddenly, this little resource became so much more than a story about uppercase and lowercase letters.
It became an opportunity to explore different kinds of compounds, the history of words, and the fascinating connections hiding beneath the surface of our language.
The finished resource is only part of the story. The real journey happens while following one question after another.
I hope it sparks curiosity, creates a few "aha!" moments, and helps others see the English language with a little more wonder. ๐
