Wikipedia says "currying or Schönfinkelisation[1] is the technique of
transforming a function that takes multiple arguments into a function
that takes a single argument" -- and FWIW I agree with Wikipedia in this
case; the reverse (going from single-arg to multiple-args) would be
"uncurrying", though I don't think I've ever used that term myself.

functools.partial's name may be more precise (because it can, e.g., go
from a function taking 3 arguments to one taking 2 -- not just from N
down to 1) but your 'pedantic' remark seems pedantically wrong:-).
