I lost a word today
and despite all my
searching it is still
on the missing list.

It was a bit like a
keystone in an arch,
the main link to a poem
I was intending to write.

I'm in Lisbon and not a
syllable of Portuguese,
so there is no point in
me putting up posters;

"English word lost
beginning with a B "

              P.S.

I made my way to Cafe
Brasileira and wrote this.
