X is for doggerel, verse or poetry

Doggerel

The worst of verse
Is called doggerel
But at least these writers
Usually Know how to spell
Doggerel writers
have no sense of rhythm

The next in merit
Is called simply verse
Moderately readable
Some pieces are much worse

The most inspiring
Is called poetry
Beginners usually
Do not aspire so high

Rhyming does not make verse
Turn into doggerel
Not rhyming does not promote
Most verse into poetry

To rhyme or not to rhyme
That is the question
Sometimes there is no time
To think much about this
