Unruly Second Sex recalled in French fantasy? (7)
I believe the answer is:
restive
'unruly' is the definition.
(thesaurus)
'second sex recalled in french fantasy?' is the wordplay.
'second' becomes 's' (common abbreviation).
'sex' becomes 'it' (a common euphemism).
'recalled' says the letters should be written in reverse (to recall can mean to bring something back).
'in' means one lot of letters goes inside another.
'french fantasy?' becomes 'reve' ('dream' in French).
'it' written backwards gives 'ti'.
's'+'ti'='sti'
'sti' placed within 'reve' is 'RESTIVE'.
(Other definitions for restive that I've seen before include "It veers around, resisting control" , "Resisting control, nervous or impatient" , "Unable to keep still" , "Unable to stay still" , "Impatient of authority" .)
