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 anagramming the letters.
'on' says to put letters next to each other.
'the middle of' says to take the centre.
The middle of 'bed' is 'e'.
'lies' anagrammed 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" .)
