She's not allowed in bed (3)
I believe the answer is:
ann
'she's' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for ann that I've seen before include "- - Jones, 1969 Wimbledon champion" , "female" , "... Margret or Hathaway" , "eg Miss Widdecombe" , "Lady's name" .)
