There is not a single word that’s universal to all languages.
Even if there had ever been one at some point, there are languages that have/had word retirement as part of the culture speaking it: If a word is used as someone’s name and that person dies, that word is now taboo and a new word is needed to refer to what the old word stood for.
Conlanging, especially by laypeople, often explicitly makes up most or all of its vocabulary from scratch or uses cyphers to make the connection invisible. I wouldn’t be surprised if a people made up their own secret language from scratch, maybe initially with very similar grammar, that developed into a native language for a community.
Have you heard of Cockney rhyming slang? Take a word like “fart”, use a two part word that rhymes with it, like “raspberry tart”, then drop the rhyming part. That leaves you with “raspberry” meaning “fart” and no discernible connection to the old words this utterance/meaning pair came from.
Sign languages are languages as well, and in multiple instances developed from the ground up without influence from the surrounding spoken languages.
