Oh, this is a type of shorthand!
There are 3 main types, but from my research, this looks to be American Gregg Shorthand.
As you can see, there are set symbols for every letter.
Letās break one of the words down:
Using the Gregg Alphabet as reference, we can see most of the letters in āatrophiedā are present. But why no āoā vowel, and why is āphā written as āfā?
Simple. In shorthand, you cut out all vowels in a word when writing it down, with the exception of words that BEGIN or END with a vowel (hence the āaā at the start being present), or like in the āiā in āatrophiedā, to make it more readable when the sound could be harder to distinguish if it isnāt written. In āatrophiedā if the the āiā isnāt written, it could be hard to tell if the writer meant a āfudā, āfadā, āfodā or āfidā sound, for example.
Also, since Shorthand is a phonetic writing system, you are encouraged to write down the phonetic sounds of words rather than the actual letter blends - in this case, write an āfā instead of a āphā.
So in actuality, these arenāt just meaningless scribbles - itās Gregg Shorthand, a writing system developed to take down notes more quickly than when written out in full, which is very useful in a medical or journalistic environment.
Some people can even write over 100 words in a minute! And, itās been in use since John Robert Gregg invented it in 1888! Wow! So old!
Isnāt language amazing~?
