Little girl sent back to bed (3)
I believe the answer is:
deb
'little girl' is the definition.
'deb' can be an answer for 'girl'. I'm not certain of the 'little' bit.
'sent back to bed' is the wordplay.
'sent back' says the letters should be written in reverse.
'bed' back-to-front is 'DEB'.
Can you help me to learn more?
(Other definitions for deb that I've seen before include "Young socialite" , "Young woman making her first appearance in society, in short" , "One coming out" , "In brief, a society girl getting out of bed" , "Girl just entering society" .)
