A cruise ending prematurely, sadly I drowned (6)
I believe the answer is:
icarus
'a cruise' is the definition.
Both the definition and answer are singular nouns.
Maybe there's an association between them I don't understand?
I don't 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 "He flew fatally close to the sun in Greek myth" , "Foolhardy flier" , "who made unwise flight?" , "he tried flying" , "one with disintegrating wings" .)
