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.
In the 13th century, Frederick II was the Holy Roman Emperor. He supposedly carried out a famous language deprivation experiment where he had infants raised by foster mothers who were not allowed to talk to them–they could only feed and bathe then. This was to see if there is a natural human language, he thought Greek or Hebrew might emerge. It turns out that the children all died. In sociology this is taught as proof that humans need language and social interaction to survive. But the whole story comes from a single Franciscan monk who was apparently not a fan of the emperor, so there’s some doubt.
I would put some doubt on that story, since most children that were born deaf still survive.
Also, in many orphanages throughout the centuries, children often didn’t get much more care than described in that experiment.
If that story is true, there was no communication with these children. But children born deaf still learn to communicate via sign language or other motions. The language becomes non-spoken, but is visual and very rich and expressive.
I am able to hold a basic conversation in British Sign Language, don’t worry, I do understand the concept.
But if you know your history, you also know that widespread sign languages are a comparatively recent thing. For most of human existence, not being able to hear/speak was equated with a mental disability. You can still see this in many languages like e.g. in the English word “dumb”, which means “not being able to speak” and “not being intelligent”.
Quite a few deaf children over the millennia grew up in severely understaffed orphanages, because their parents didn’t want to raise a deaf child that would never return their investment. And still many of these children did grow up, in spite of never learning any meaningful language.
Sadly enough, we have a similar case in the extended family. They have a child that was born deaf, but he was only diagnosed as deaf at the age of 4 (it still baffles me how it’s possible for parents to not notice that their <4 year old can’t hear them). His vision is also severely impaired. His parents are conspiracy theorists, so they didn’t believe the doctors and they didn’t accept any medical/psychological/pedagogic help for this kid.
He’s now in his mid 20s, and he can still not communicate in any meaningful way, because he never learned to. He is now in some form of daycare, and the staff there told the parents that he is too old to learn any meaningful form of communication, because he didn’t when his brain was young enough to learn the concept of languages (signed or spoken).
But, I digress: My original mentioning of deaf people was to disprove that it “not hearing spoken language kills children”. But the second point that I brought up (children growing up in orphanages where they are massively neglected) is something that nobody picked up, even though that’s the stronger point.
