Argue about being put in poor side (7)
I believe the answer is:
dispute
'argue about' is the definition.
'dispute' can be an answer for 'argue' (disputing is a kind of arguing). I'm not sure about the 'about' bit.
'put in poor side' is the wordplay.
'in' is an insertion indicator.
'poor' is an anagram indicator.
'side' anagrammed gives 'dise'.
'put' inserted inside 'dise' is 'DISPUTE'.
'being' acts as a link.
Can you help me to learn more?
(Other definitions for dispute that I've seen before include "Altercate" , "Disagree or challenge" , "Question or deny accuracy or validity" , "Row" , "Altercation" .)
