'ancient greek poet of lesbos' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for sappho that I've seen before include "Pa hops around the ancient Greek poetess" , "Greek female poet" , "Ancient Greek poet of Lesbos" , "Greek poetess; has pop (anag.)" , "Greek lyric poet of Lesbos" .)
