Related to the question about whether facial expressions are universal.
Are there words/verbal expressions/sounds that exist in every language and have the same meaning in every language?
(I’d also count words that are very similar.)
One example, that I believe is universal is M followed by a vowel followed by another M and optionally another vowel, meaning “Mother”.
At least in any language I know, this seems to hold true (mom, Mama, mamma, Mami, …).
Any other examples?
Edit: To clarify, I am not looking for very popular words that have been imported into most languages (like how almost everyone worldwide knows what Ketchup is), but about words that are “native” to humans. So if you pick someone from an uncontacted native tribe and tell them nothing, they would be able to understand/use that word/sound/verbal expression.
The closest thing to a universal word is a scream. After some experience nearly all humans–regardless of region or native languages–can tell the difference between a scream of sudden fear and the scream of a mother who’s child just died.
The scream of pain is a bit cultural/regional (“ow!”, “fuck!”, “damnit!”) but I’m guessing most humans could tell what someone means when they shout any given sound or word after accidentally banging their finger with a hammer or stepping on a lego brick while barefoot.
