A clean slate; the mind of the newly born, all innocent and as yet untouched by experience.
Uninformed.
Bit like me when I arrived here.
(Well, that didn't last long, did it...)
Or perhaps an opportunity for a new beginning. (Some definitions even encompass a need for a new beginning.)
Wash away all the old baggage and let the ideas spring up afresh.
This was going to be a bit of a gardening column today as OH used this phrase to describe the southwest corner of our garden now that it has been cleared of its prickly thickety shrubs. I wondered idly whether he was getting mixed up with 'razed to the ground' but although there may be a connection the phrase does fit. (Yeah, I know, spot the word nerd...)
Cleared ground, all ready for new things to grow.
And only the sparrows and perhaps a few homeless woodlice regretting the old rubbish that has gone.
But then who wants to read or even write a gardening column when there is slash to be enjoyed instead?
I'm off to remove some breeches...
