Being extra-playful when topless is more perilous (7)
I believe the answer is:
riskier
'more perilous' is the definition.
(I've seen this in another clue)
'being extra-playful when topless' is the wordplay.
I cannot really see how this works, but
'being' could be 'skier' (skier is a kind of being) and 'skier' is found in the answer.
This explanation may well be incorrect...
'is' is the link.
Can you help me to learn more?
(Other definitions for riskier that I've seen before include "More likely to cause loss" , "less safe" , "More chancy" .)
