There was a man in the moon,
Who switched the lights off too soon,
Day turned to night,
All people in fright,
Running in fear of the doom.
This type of poem is called a limerick. It was made popular by Edward Lear in the 19th century. I just love these types of poems. They are great fun to write because of the clear structure and rhyme pattern.
A limerick has five lines with a clear AABBA rhyme pattern:
There was a man in the moon, A
Who switched the lights off too soon, A
Day turned to night, B
All people in fright, B
Running in fear of the doom. A
and a da-de-da-de-da, da-de-da-de-da, de-da-de-da, de-da-de-da, da-de-da-de-da rhythm to it.
Why don’t you have a go?
