She lies awkwardly on the middle of the bed (5)
I believe the answer is:
elsie
'she' is the definition.
'lies awkwardly on the middle of the bed' is the wordplay.
'awkwardly' indicates an anagram.
'on' means one lot of letters go next to another.
'the middle of' says to take the centre.
The middle of 'bed' is 'e'.
'lies' with letters rearranged gives 'elsi'.
'elsi'+'e'='ELSIE'
(Other definitions for elsie that I've seen before include "Lady" , "Girl's name" , "Female name; rhymes with London football team" , "woman" , "Name for girl" .)
