Could one ramble around in such halls? (6)
I believe the answer is:
marble
'could one ramble around in such halls?' is the definition.
I can't judge whether this definition defines the answer.
'could one ramble' is the wordplay.
'could one' indicates anagramming the letters (I've seen this in other clues).
'ramble' with letters rearranged gives 'MARBLE'.
Can you help me to learn more?
(Other definitions for marble that I've seen before include "Rock used for building and sculpture" , "Hard crystalline limestone used for sculpture" , "Hard crystalline limestone, can be polished" , "Small ball of glass used in games" , "Polished rock used in sculpture" .)
