Less inhibited about blocking rise of judge (5)
I believe the answer is:
freer
'less inhibited' is the definition.
(I've seen this before)
'about blocking rise of judge' is the wordplay.
'about' becomes 're' (regarding).
'blocking' means one lot of letters goes inside another (block can mean to plug a gap in something).
'rise of' is a reversal indicator (in a down clue, letters go up).
'judge' becomes 'ref' (referee).
'ref' reversed gives 'fer'.
're' going inside 'fer' is 'FREER'.
(Other definitions for freer that I've seen before include "Less constrained" , "More at liberty, less restrained" , "Less restricted" , "less inhibited" .)
