Murmur

Can anyone tell me if there is a term for the study of words that have multiple, consecutive, identical syllables such as the word "murmur". Additionally, can anyone think of other such words that are not nonsensical words.

Tomtom, frou-frou, tutu, juju, berber, dada, ack-ack, maumau, plenty of babytalk examples like mama, papa and booboo and the majorly cheating hotshots (*grin*), to name a few. There'll be plenty more, I'm sure.

If there *isn't* "a term for the study of words that have multiple, consecutive, identical syllables" I would like to nominate "ologyology."
