What is currying?

Currying is the technique of breaking down functions that take multiple arguments into functions that take a single argument (monads).

Take the following definition of a function that takes two arguments:

f(A, B) → C

If we were to curry the above function we would describe it in the following way:

f(A) → g(B) → C

Where the functions f and g are now monads.
