Georgia changes gear in petrol station (6)
I believe the answer is:
garage
'petrol station' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'georgia changes gear in' is the wordplay.
'georgia' becomes 'ga' ().
'changes' indicates an anagram.
'in' indicates putting letters inside.
'gear' with letters rearranged gives 'rage'.
'ga' put within 'rage' is 'GARAGE'.
Can you help me to learn more?
(Other definitions for garage that I've seen before include "Building for housing automobiles" , "Building for vehicles" , "Motor sales and service here" , "Where car is housed" , "Car repair shop" .)
