The Cablese/Telegraphese is more interesting than the use in LLM. DuckDuckGo'ed "paromella":

https://en.wikipedia.org/wiki/Commercial_code_(communication...

Some codes I found interesting:

> INSANE - at what price, free on board and freight, can you offer us cotton for shipment by steamer sailing this week?

> COGNOSCO - dining out this evening, send my dress clothes here

Useful codeword!

> ANNOSUS — Confined yesterday, Twins, both dead, Mother not expected to live

How often did that one come into use??
