Political philosopher worries about Republican group causing riot? (4,8)
I believe the answer is:
marx brothers
'riot?' is the definition.
Both the definition and answer are singular nouns.
Maybe there's an association between them I don't understand?
'political philosopher worries about republican group' is the wordplay.
I cannot really understand how this works, but
'philosopher' could be 'marx' (Karl Marx) and 'marx' is found within the answer.
'republican' could be 'r' (abbreviation in US politics) and 'r' is located in the answer.
The remaining letters 'bothers' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'causing' acts as a link.
Can you help me to learn more?
(Other definitions for marx brothers that I've seen before include "Groucho, Harpo, Chico, Zeppo and Gummo, but not Karl" , "Film comedians" , "Film family" .)
