[Haskell-cafe] special term describing f :: (Monad m) => (a -> m b)?

What is a function of the followning type called:

f :: (Monad m) => (a -> m b)

Is there a special term describing such a function (a function into a monad)?

For f in a >>= f is en example.

Need it for an article/report.

Well, formally, it's called a Kleisli arrow (or morphism). A less formal term commonly used for values of type a -> m b and m b, is 'computation' or'action' (though 'action' is usually used for the specific case of IO). In "Notions of Computation and Monads" Moggi calls them 'commands'.
