Circum is a prefix
Whose presence does effect
In many ways its second part,
For instance: Circumspect.
If Circum is added to
A position in a dance
You will find that you have made
A unique circumstance.
If instead you circum
A trip to another state
You might be delighted
That you can circumnavigate.
There are circum words
That most people can’t define
Like circumference and circumscribe
And circumquasiredefine.
But there’s a word that to circum
Would not be very wise.
You may have guessed by now
That that word, of course, is “size.”
