A comfy little place in Sydenham (3)
I believe the answer is:
den
'a comfy little place' is the definition.
'den' can be an answer for 'place' (den is a kind of place). I am not certain of the 'a comfy little' bit.
'in sydenham' is the wordplay.
'in' indicates the answer is hidden within the clue.
'DEN' is hidden within 'sydenham'.
Can you help me to learn more?
(Other definitions for den that I've seen before include "Home of the beast" , "Room for work or play" , "Animal's lair or gent's study" , "Animal's lair or man's study" , "Animal shelter" .)
