Mama and papa
In linguistics, mama and papa are considered a special case of false cognates. In many languages of the world, sequences of sounds similar to /mama/ and /papa/ mean "mother" and "father", usually but not always in that order. This is thought to be a coincidence resulting from the process of early language acquisition.[1][2][3][4]
