Don’t heed me now. I’m no authority
on building rhyme and specifying how
one might’s well work at writing poetry.
Don’t heed me now.

The syntax needs be natural. I’ll allow
a word’s reflecting etymology
(its present obsolete or middlebrow).

But don’t abuse good sense or sanity,
and let’s play pen with this essential vow:
to ply with caution the apostrophe.
(Don’t heed me now).

(Roundel)
