Legendary high-flier who went down to the sea (6)
I believe the answer is:
icarus
'legendary high-flier' is the definition.
'icarus' can be an answer for 'high-flier' (I've seen this before). I'm not sure about the 'legendary' bit.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for icarus that I've seen before include "foolish high-flier" , "His false wings melted" , "Unfortunate high-flier in Greek mythology" , "Ancient Greek who flew too close to the sun" , "Foolhardy flier" .)
