Mama can be considered a universal language that belongs to no particular region. It’s often the first two syllabic word of a baby, alongside “papa” and “baba”. When a child starts learning how to talk, he or she starts saying “ma” and “pa” first, those seem really be true simple for the child to say at that stage, hence “mama” and “papa” depending on which a child learns to say first. A child is often not taught how to say these two words, they just grow up to say them by nature.
