A 14th century farm arse is an animal's
and the 14th century too gave us
a bum, a buttock, or a butt,
all not rude.
To be polite,
a 16th century
backside
was a posterior.
In the 18th century,
we had bottoms, behinds,
or borrowed words, gluteus maximus and derrière.
No 19th century ass was impolite, but poor arse
appears here to shock.
And now?
So many rude, and not, arses and asses to plow through.
