Footwear found in the petrol station (5)
I believe the answer is:
pumps
This clue might be a double definition.
'footwear' is the first definition.
(pumps is a kind of footwear)
'petrol station' is the second definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'found in the' acts as a link.
Can you help me to learn more?
(Other definitions for pumps that I've seen before include "footwear" , "Dancing shoes - may be manned!" , "Moves fluid or gas by pressure or suction" , "Questions persistently; light shoes" , "Mechanical devices that move fluid or gas" .)
