Say, what could be in quotes? (8)
I believe the answer is:
question
'say' is the definition.
(thesaurus)
'what could be in quotes?' is the wordplay.
'what could be' indicates anagramming the letters.
'in'+'quotes'='inquotes'
'inquotes' is an anagram of 'QUESTION'.
(Other definitions for question that I've seen before include "Pump" , "Enquiry; doubt" , "motion for debate" , "Query" , "Interrogate or express doubt about" .)
