Eccentric grandee touring Spain with extremely talkative deviant (10)
I believe the answer is:
degenerate
'deviant' is the definition.
(I know that deviant can be written as degenerate)
'eccentric grandee touring spain with extremely talkative' is the wordplay.
I cannot quite understand how this works, but
'spain' could be 'e' (abbreviation for Espana) and 'e' is found in the answer.
an anagram of 'grandee' is 'dgenera' which is located in the remaining letters.
The remaining letters 'te' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for degenerate that I've seen before include "Mean" , "Decline physically or morally" , "dishonourable" , "sink" , "In moral or physical decline" .)
