The interfering fellow figures in mere chaos! (7)
I believe the answer is:
meddler
This clue could be a double definition.
'the interfering fellow' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'figures in mere chaos' is the second definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's an association between them I don't understand?
Can you help me to learn more?
(Other definitions for meddler that I've seen before include "One interfering" , "Busybody (not fruit!)" , "Interfering person" , "One who interferes" , "Interferer" .)
