Write
(ME. Written, OE. writan, to scratch, to score, akin to G. reissen, to tear)

The epic poem I finished Wednesday
disintegrated to ten lines Thursday.
By Friday it was down to three.

I wrote on.  

Saturday had me dispensing with the impetus
of the poem. I was left with the title
which I’d only vaguely thought out.

It is now Sunday, late at night.
I have been writing all day
and I am down to the wrong word.

All my poems end with that word.
