“Mortician” is another Gobbledygook Word, 1895.

The word “Mortician” was first printed in the February 1895 issue of Embalmers Monthly, where it was proposed as a replacement for “undertaker” or “funeral director.”
People outside the industry didn’t much care for it, complaining that it “grates the ear.”
For decades afterward it was called “ugly,” “affected,” an “uncouth stranger,” and an “atrocity” of a euphemism.
The literary critic Harry Levin called it a “pseudo-Latinism of dubious currency.”
