Left's piercing protestation disrupted filling here? (6,7)
I believe the answer is:
petrol station
'filling here?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'left's piercing protestation disrupted' is the wordplay.
'left' becomes 'l' (common abbreviation).
'piercing' indicates putting letters inside (some letters pierce a hole in a word).
'disrupted' indicates an anagram.
'protestation' anagrammed gives 'petrostation'.
'l' put within 'petrostation' is 'PETROL STATION'.
Can you help me to learn more?
(Other definitions for petrol station that I've seen before include "Filling up location?" , "Fuel supplier" , "Place to fill the tank" .)
