A euphemism is a nice way of saying something... It all depends on what your "other words" are, and in many cases if there is one euphemism for something, there are also several more.
The euphemism for "criminal" could be "wrongdoer" or "offender."
A euphemism is a word that is meant to imply another in a way that is slightly less harsh or direct. One euphemism for prison, jail, rehabilitation center or penitentiary could be "pen."
Peculiar can be considered a euphemism for the other three, so that means one of the other three would not be one.

A euphemism is a polite, socially acceptable way of naming something else. For example, a public toilet being called a "comfort station", or "Sailsbury steak" as a euphemism for a hamburger.
