Dare to say a daughter started exploit (9)
I believe the answer is:
adventure
'dare' is the definition.
(thesaurus)
'a daughter started exploit' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'started exploit' becomes 'venture' (I can't justify this - if you can you should believe this answer much more).
'a'+'d'+'venture'='ADVENTURE'
'to say' acts as a link.
Can you help me to learn more?
(Other definitions for adventure that I've seen before include "Exciting or daring experience" , "Dangerous undertaking" , "that may be exciting" , "Hazardous operation" , "Exciting or dangerous journey" .)
