Involving two sides of broken aspirin tab (10)
I believe the answer is:
bipartisan
'involving two sides' is the definition.
I can't tell whether this definition defines the answer.
'broken aspirin tab' is the wordplay.
'broken' indicates anagramming the letters.
'aspirin'+'tab'='aspirintab'
'aspirintab' is an anagram of 'BIPARTISAN'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for bipartisan that I've seen before include "Like a coalition government" , "Associated with two parties" , "Involving agreement across political divides" , "supported by two political parties!" , "between political groups" .)
