Big film, new in middle of week, featuring both sexes (7)
I believe the answer is:
epicene
'featuring both sexes' is the definition.
I can't tell whether this defines the answer.
'big film new in middle of week' is the wordplay.
'big film' becomes 'epic'.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'in' is an insertion indicator.
'middle of' means to look at the middle letters.
The centre of 'week' is 'ee'.
'n' inserted within 'ee' is 'ene'.
'epic'+'ene'='EPICENE'
Can you help me to learn more?
(Other definitions for epicene that I've seen before include "Having characteristics of both sexes - or of none" , "Hermaphroditic" , "Sexless" , "Metrosexual" , "Common to both sexes" .)
