Emotionally affected without end — you got me (6)
I believe the answer is:
touche
'you got me' is the definition.
('touche' is said to acknowledge a fair point)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for touche that I've seen before include "Fencing call" , "Fencing cry" , "That hit home" , "Acknowledgment of a hit in fencing" , "Acknowledgement of fencing hit or valid criticism" .)
