Do water sport? Avoid losing power (3)
I believe the answer is:
ski
'do water sport?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'avoid losing power' is the wordplay.
'avoid' becomes 'skip' (skip can mean to avoid or pass over).
'losing' indicates named letters should be taken away.
'power' becomes 'p' (symbol in physics).
'skip' with 'p' removed is 'SKI'.
Can you help me to learn more?
(Other definitions for ski that I've seen before include "Aid to movement on snow" , "Winter sport accessory" , "What one might do in Alps" , "Snow-runner" , "Sliding runner" .)
