Put in an order, as planned (8)
I believe the answer is:
arranged
'planned' is the definition.
(I've seen this before)
'put in an order' is the wordplay.
'put' becomes 'arrange' (arranging is a kind of putting).
'in an order' becomes 'd' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'arrange'+'d'='ARRANGED'
'as' is the link.
Can you help me to learn more?
(Other definitions for arranged that I've seen before include "Ordered" , "Put in proper order" , "Fixed" , "Put in order or adapted a piece of music" , "Settled plans for something" .)
