Sort of at risk, we participate in sport (5-3)
I believe the answer is:
water-ski
'sport' is the definition.
(I've seen this before)
'sort of at risk we' is the wordplay.
'sort of' indicates anagramming the letters.
'at'+'risk'+'we'='atriskwe'
'atriskwe' with letters rearranged gives 'WATER-SKI'.
'participate in' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for water-ski that I've seen before include "Aquatic sport accessory" , "Engage in aquatic sport" , "Get towed behind a motorboat" , "Item used in aquatic sport" , "To ride behind a speedboat" .)
