Puts to rest every agreement? (6)
I believe the answer is:
allays
'puts to rest' is the definition.
(I've seen this in another clue)
'every agreement?' is the wordplay.
'every' becomes 'all' (similar in meaning).
'agreement?' becomes 'ays' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'all'+'ays'='ALLAYS'
Can you help me to learn more?
(Other definitions for allays that I've seen before include "Soothes, eases" , "Puts at rest, say fears" , "Assuages, eases" , "Calms" , "Diminishes or puts at rest" .)
