The ignoring of many a confused issue (6)
I believe the answer is:
disuse
'the ignoring' is the definition.
I can't tell whether this definition defines the answer.
'many a confused issue' is the wordplay.
'many' becomes 'd' ().
'a confused' indicates an anagram.
'issue' anagrammed gives 'isuse'.
'd'+'isuse'='DISUSE'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for disuse that I've seen before include "State of not being employed" , "Fall into this state to be unemplyed? (6)." , "Issued (anag)" , "Neglect; abandonment" , "Neglect; desuetude" .)
