Pool power, heading off confusion (6)
I believe the answer is:
puddle
'pool' is the definition.
('puddle' can be a synonym of 'pool')
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for puddle that I've seen before include "Little bit of water" , "Small amount of standing rainwater" , "Small pool of muddy water" , "Standing rain water" , "Small amount of standing water" .)
