As Spooner sings hackneyed song, somewhere to relax (4,5)
I believe the answer is:
easy chair
'as spooner sings hackneyed song' is the definition.
I can't tell whether this definition defines the answer.
'somewhere to relax' is the wordplay.
'somewhere' becomes 'chair' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to' means one lot of letters go next to another (I've seen this in other clues).
'relax' becomes 'easy' (I've seen this in another clue).
'chair' put after 'easy' is 'EASY-CHAIR'.
Can you help me to learn more?
(Other definitions for easy chair that I've seen before include "Comfy seat" , "comfortable position" , "nice spot to be in" , "source of comfort" , "Comfortable place to relax" .)
