Handle an eccentric (5)
I believe the answer is:
crank
This could be a double definition.
'handle an' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'eccentric' is the second definition.
(crank is a kind of eccentric)
Can you help me to learn more?
(Other definitions for crank that I've seen before include "Turn a handle - weirdo" , "Eccentric - starting handle" , "Wind (up) - oddball" , "Person with strange ideas, or machine part" , "Turn (engine handle); eccentric" .)
