Rings about destination of pillow-blocks (9)
I believe the answer is:
pedestals
'pillow-blocks' is the definition.
I can't judge whether this definition defines the answer.
'rings about destination' is the wordplay.
'rings' becomes 'peals' ('peal' can be a synonym of 'ring').
'about' indicates putting letters inside.
'destination' becomes 'dest' (I can't justify this - if you can you should give a lot more credence to this answer).
'peals' placed around 'dest' is 'PEDESTALS'.
'of' is the link.
Can you help me to learn more?
(Another definition for pedestals that I've seen is " Supports, foundations".)
