Today it seems to be carpenter meaning framer or "rough" carpenter. Other than that it's "finish" carpenter or "cabinet maker".
Then I'll amend my observation to saying that, IMHO, framing carpentry isn't that hard, but finish carpentry is another matter. I think the term "jointer" may have gone by the wayside with timber frame construction, when there was a person of greater skill and experience than a "common carpenter", who was charged with the critical forming and fitting of the mating parts of the posts and beams.
