In the case of the 11 babies born at once, according to Oakton, there is a Latin prefix called "deca" (meaning "10") and following that is the term "hendec" that means "11."
Adding to this, there is also a prefix for "more than 10" or "eleventh" in Latin called "unden" taken from the term "undecim."
For these reasons, if 11 babies are born at once in the future -- the world could start to hear a new word used to refer to them. Since the total number in the birth is 11 and "-uplets" is traditionally the suffix added to the Latin term for the number of babies -- it is possible the parents or the media will call them "undenuplets" or "henduplets."
