Bold Latin city is unsettling (8)
I believe the answer is:
perturbs
'is unsettling' is the definition.
I can't tell whether this defines the answer.
'bold latin city' is the wordplay.
I cannot really understand how this works, but
'bold' could be 'pert' (I've seen this in another clue) and 'pert' is found within the answer.
'city' could be 'ur' (ancient Sumerian city state) and 'ur' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for perturbs that I've seen before include "Disquiets, troubles" , "Makes anxious and uneasy" , "is upsetting" .)
