Longfellow lover (9)
I believe the answer is:
minnehaha
'longfellow lover' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for minnehaha that I've seen before include "Lover of Hiawatha" , "Hiawatha's love" , "American Indian woman" , "Native American woman" , "Hiawatha's lover (Longfellow)" .)
