Euphemisms can evolve over time: Moron used to be the
euphemism for idiot. Then moron became offensive, so the euphemism for
moron became retarded. Now retarded is considered offensive, so the euphemism
is mentally challenged or special.
A similar thing has occurred with crippled -> handicapped
-> disabled. (Thanks to Wikipedia
for the info.)
Euphemisms II. Copy and translate. Most translations will be a phrase rather than a word.
