Lies down in the forest, silent (5)
I believe the answer is:
rests
'lies down' is the definition.
(I've seen this in another clue)
'in the forest silent' is the wordplay.
'in' says the answer is hidden in the clue.
'RESTS' can be found hidden inside 'forest silent'.
(Other definitions for rests that I've seen before include "Musical pauses" , "Takes a break" , "Reposes" , "holidays" , "Pauses; relaxes" .)
