telegraphese. didn't know of it

Here https://en.wikipedia.org/wiki/Telegram_style

The cost of sending a telegram became expensive over time. The length And word count of a telegraph was at a premium. So, like early 2000s text messaging (to save space and data charges, as well as message limitation(s) (which used to be like 140 char)), people would abbreviate. And also come up with one-of-a-kind terms used nearly exclusively while sending a telegram.

So this is effectively a human phenomena (well, as is writing) – save space, be economic, brevity and slang.

Amen

Also, I discovered this when looking into QSL codes (HAM radio) and also brevity codes. I want to make something similar to a HAM QSL card for he x2600 site, as I already think of x2600 as a call sign
