Multidisciplinary — multi (many), disciplinary (pertaining to discipline). Many disciplines! Sounds excessive! Abuse maybe?
Or…since a disciple is a follower, perhaps multi-disciplinary refers to a charasmatic leader such as the Pied Piper of Hamelin?
Or…since a discipline can be a branch of knowledge, maybe pertaining to many areas of knowledge? Hmmmm….I like that. Let’s go with that!
