Youth of Abydos in Greek mythology who drowned in the Hellespont (7)

I believe the answer is:

leander

(Other definitions for leander that I've seen before include "Hero-worshipper" , "Hellespont swimmer" , "In Greek legend, lover of Hero who drowned in the Hellespont" , "Hero's mate" , "Heroic lover" .)

I've seen this clue in The Mirror.
