Not nearby? About to keep volume raised (6)
I believe the answer is:
remote
'not nearby? about to keep volume raised' is the definition.
I can't tell whether this definition defines the answer.
'nearby? about to keep volume raised' is the wordplay.
'nearby? about' becomes 're' (regarding. I am not sure about the 'nearby?' bit.).
'to keep' indicates putting letters inside.
'volume' becomes 'tome' (a tome is a large or heavy book).
'raised' is a reversal indicator (going up in a down clue).
'tome' back-to-front is 'emot'.
're' enclosing 'emot' is 'REMOTE'.
Can you help me to learn more?
(Other definitions for remote that I've seen before include "device used by couch potato?" , "as from armchair to TV?" , "Far-off" , "Distant, aloof" , "Slight possibility" .)
