Last word of "Ulysses"
I believe the answer is:
yes
'last word of ulysses' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for yes that I've seen before include "Oui" , "Aye" , "That's 27 [RIGHT]" , "Affirmative reply" , "One response to "will you marry me?"" .)
