When I was learning the pertinent physics (1960s), it seems to me that the word "transform" (as a noun) was reserved for a change of variable which changed the type of function being considered (e.g. Fourier and Laplace transforms change time functions into related frequency functions). The word "transformation" (as a noun) was reserved for coordinate transformations, which, for the same function, expressed the same point in space (or space time) in different coordinates (e.g. spherical coordinate transformation or Lorentz transformation).

We speak of Fourier transforms but Lorentz transformations.
Do you think there’s a difference (in mathematical physics) between a
“transform” and a “transformation”?
