Right-winger supporting professional male working in coastal area (10)
I believe the answer is:
promontory
'coastal area' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'right-winger supporting professional male working' is the wordplay.
'right-winger' becomes 'Tory' (Tory is an example).
'supporting' is a charade indicator (letters next to each other) (in a down clue, some letters go below others).
'professional' becomes 'pro' (abbreviation).
'male' becomes 'm' (common abbreviation).
'working' becomes 'on' (on can mean working or activated).
'pro'+'m'+'on'='promon'
'tory' put after 'promon' is 'PROMONTORY'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for promontory that I've seen before include "Point" , "Head" , "Coastal feature" , "Bill" , "Headland" .)
