Offside  

O writers of song, verse, and drama,    

relators of life’s joy and trauma,

lest your meaning be missed

never fail to enlist

a strategically placed Oxford comma.

Preposition

What’s a preposition?

Perhaps you wish you knew.

That word contains a second one,

providing quite a clue.

For on or in or under

and behind, beneath, below,

all tell us just where something is—

POSITION—

Now you know!
