Members of union run into worries (8)
I believe the answer is:
brothers
'members of union' is the definition.
The definition and answer can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?
'run into worries' is the wordplay.
I cannot really see how this works, but
'run' could be 'r' (cricket abbreviation) 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...
Can you help me to learn more?
(Other definitions for brothers that I've seen before include "See 5" , "(Roman Catholic) monks" , "See 8" , "Male siblings" , "Brethren" .)
