I count notes that may be disputable (11)
I believe the answer is:
contentious
'disputable' is the definition.
Both the definition and answer are adjectives. Perhaps there's a link between them I don't understand?
'i count notes that may be' is the wordplay.
'that may be' is an anagram indicator.
'i'+'count'+'notes'='icountnotes'
'icountnotes' anagrammed gives 'CONTENTIOUS'.
Can you help me to learn more?
(Other definitions for contentious that I've seen before include "debatable" , "Likely to cause disagreement" , "controversial" , "Likely to cause an argument" .)
