Possibly flyer’s getting new blue cape (10)
I believe the answer is:
promontory
'cape' is the definition.
(thesaurus)
'possibly flyer's getting new blue' is the wordplay.
I cannot really see how this works, but
'new' could be 'n' (abbreviation as in New Testament NT) and 'n' is found within the answer.
'blue' could be 'tory' (I've seen this before) and 'tory' is found within the answer.
The remaining letters 'promo' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for promontory that I've seen before include "Headland" , "Head" , "Bluff" , "Point" , "Coastal feature" .)
