I never claimed to invent the term monad. I did invent the term operad, as a portmanteau of operation and monad. And I convinced MacLane to change from the silly term `triple' to `monad' in Categories for the working mathematician. He is not here to corroborate, but look at his note on terminology, page 138 of the second edition: ``The frequent but unfortunate use of the word `triple' in this sense has achieved a maximum of needless confusion, what with the conflict with ordered triple, plus the use of associated terms such as ``triple derived functor''for functors which are not three times derived from anything in the world. Hence the term monad.'' Michael, shame on you! Peter May
