Apostrophilia 

How misused the
apostrophe
it’s never where
it’s meant to be

It shows up in
plurality
by twos and threes
annoyingly

Its ownership
to misconstrue
is sure, I’ll grant
easy to do

It goes in where
a letter don’t
(I’ll not correct that
if you won’t!)

It makes a word
out of two others
or adds a letter
to another’s

Its proper use
is plain to see
so do not fear
apostrophe
