Unfortunately, you are likely wrong. “Abbreviation” — to my knowledge — is a borrow from French and simply means to shorten in time or length; nothing about words specifically, as you are suggesting.
“Abbreviation, N., Etymology.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/8875868501.
Pre-word meaning: “Abbreviation, N., Sense 1.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/1149358652.
Word meaning: “Abbreviation, N., Sense 2.b.” Oxford English Dictionary, Oxford UP, June 2024, https://doi.org/10.1093/OED/3259923213.
It’s worth noting that the OED is, in its nature, a descriptive dictionary; therefore, this rather general definition should be taken with a grain of salt. The word may — indeed, as it is common — have a more specific meaning, as you suggest.
Edit:
Nope, you were definitely wrong (this time a free dictionary!):

Yeah, I second this. You may want to look in to DEs/WMs like DWM ©, Xmonad (Haskell), and AwesomeWM (lua) that let you customize them through programming.
