Does it plug the generation gap? (6)
I believe the answer is:
dynamo
'gap?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's a link between them I don't understand?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for dynamo that I've seen before include "something electrifying" , "Small generator" , "Producer of electrical energy" , "Electricity generator or energetic person" , "Juice supplier" .)
