The unit is called Anapest:
Two syllables weak and one stressed.
Make your lines twos and threes,
(Fudge a bit if you please),
And everyone will be impressed.
I've only got one thing to add:
In poetry it drives me mad
When scurrilous cheaters
To flesh out their metres
Add fillers like Praswell. It's bad.
I'll tell you which ones make me sore:
There's "and" and there's "just;" I deplore
Most of all in a rhyme
To see "that" in a line
Where no "that" was e'er seen before.
Please allow me, Miss Foot, to object.
The word "and" is a word to respect!
Would our language without it
Be so useful? I doubt it,
And its use here is wholly correct.
I have no critique of your use
Of "and;" it provides you with juice
To power your rhyme
'Stead of just marking time,
But elsewhere I've seen this abuse.
This "and"'s found most often in urinals
Where bored, drunken poets diurnal
Will flesh out a beat
While wetting their feet
To make Awful Poetry Journals.
It's a dumb reason to be complaining,
But I'm finding your line-splitting draining.
I don't mean to bitch,
But it's making me twitch.
Will you please just stop leaving me.....
hanging?
(As I think that you already knew,
That last poem just wasn't true.
But an elegant rhyme
Is just so hard to find,
I can never resist one. Can you?)
