After some relief a number relaxed (5)
I believe the answer is:
eased
'relaxed' is the definition.
(I've seen this before)
'after some relief a number' is the wordplay.
'after some relief' becomes 'ease' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'a number' becomes 'D' (D is an example).
'ease'+'d'='EASED'
Can you help me to learn more?
(Other definitions for eased that I've seen before include "became less tight" , "Relieved, mitigated" , "Alleviated" , "Released pressure" , "Oiled" .)
