Like a butterfly, or a like bee 
Like an ant, as busy as can be
These little words we call the "busy P's"

PREPOSITIONS

Nine or ten of them 
Do most all of the work 
OF, ON, TO, WITH, IN, FROM 
BY, FOR, AT, OVER, ACROSS 
And many others do their jobs, 
Which is simply to connect 
Their noun or pronoun object 
To some other word in the sentence.

Busy P's, 
If you please. 
"ON the top is where you are!" 
Top relates TO where you are. 
"WITH a friend you'll travel far!" 
WITH a friend you'll go. 
"If you try you know that you can fly

OVER the rainbow!"

OVER the rainbow is where you can fly.

Busy PREPOSITIONS,

Always ON the go.

LIKE a bunch of busy bees,

Floating pollen ON the breeze.

Buzzing OVER the meadows,

BEYOND the forest,

THROUGH the trees,

INTO the beehive.

Busy, busy P's

IN, TO, BEYOND, OVER, ON, THROUGH!

Busy PREPOSITIONS always out in front,

ON the edges, IN the crack.

'ROUND the corner, FROM the back.

IN between the action.

Stating clearly TO your satisfaction,

The location and direction.

PREPOSITIONS give specific information.

Though little words they are,

They never stand alone

Gathering words behind them,

You soon will see how they have grown

Into a parade; a prepositional phrase.

With a noun, or at least a pronoun, bringing up the rear.

A little phrase of two or three or four or more words.

PREPOSITIONS! Attention! Forward, March!

Busy prepositions,

Always ON the march.

Like a horde of solider ants,

Inching bravely forward ON the slimmest chance

That they might better their positions.

Busy, busy PREPOSITIONS.

In the air, on the ground, everywhere.

The sun sank lower iN the west.

"IN the west it sank."

And it will rise IN the morning,

And will bring the light of day;

We say the sun comes up in the east every day!

"IN the east it rises."

Busy PREPOSITIONS,

Busy, busy, busy!

ON the top is where you are!

ON the top.

If you try you know that you can fly!

Fly where? OVER the rainbow.
