Females primarily of dubious morality must include one? (7)
I believe the answer is:
floosie
'females primarily of dubious morality must include one?' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'females primarily of dubious morality must include one?' is the wordplay.
'primarily' indicates taking the first letters.
'of dubious morality' becomes 'loose'.
'must include' indicates putting letters inside.
'one?' becomes 'i' (Roman numeral).
The initial letter of 'females' is 'f'.
'loose' enclosing 'i' is 'loosie'.
'f'+'loosie'='FLOOSIE'
(Other definitions for floosie that I've seen before include "One of the Loose Women" , "Disreputable woman" .)
