Grammatical reduplication is often used in Australian aboriginal languages to indicate plurality or magnitude. For example, the place name Wagga Wagga means place of many crows.

Reduplication is used for different things, e.g., making words plural, present-past distinction, etc.

I knew reduplication was used in Greek to form the Perfect, but it still seems too clinical, matter of fact and grammatical a word to use for poetical nonsense where it is the sheer joy of the juxtaposed similar sounds, and not their meaning, that is the reason for doing it.
