Chambers Ignores Chaucer Poem by Douglas Scotney

I may need to tell you
that a sword
was once called a swerd -
they might even have said the w.

I'm not sure if at any time
they said 'ook' for 'oak';
but Chaucer did -
probably for the sake of rhyme.

He said a knight's swerd's least strook*
would have easily felled an ook.

Chaucer's sake-of-rhyme stuff
had Chambers saying 'enough's enough'.

* 'strook' is in Chambers for 'stroke'
and for 'struck';
but for 'oak' there is no 'uck'
