Form of enquiries, not bothered about answer? (13)
I believe the answer is:
questionnaire
'form' is the definition.
(questionnaire is a kind of form)
'enquiries not bothered about answer?' is the wordplay.
'bothered' is an anagram indicator.
'about' indicates putting letters inside.
'answer?' becomes 'a' (abbreviation eg in Q and A).
'enquiries'+'not'='enquiriesnot'
'enquiriesnot' is an anagram of 'questionnire'.
'questionnire' going around 'a' is 'QUESTIONNAIRE'.
'of' is the link.
(Other definitions for questionnaire that I've seen before include "Survey answer sheet" , "List of inquiries" , "List of enquiries" , "Form for collecting data" , "Survey fill-in form" .)
