Put in order but need a ten to be included (8)
I believe the answer is:
neatened
'put in order' is the definition.
(I've seen this in another clue)
'need a ten to be included' is the wordplay.
'to be included' indicates putting letters inside.
'a'+'ten'='aten'
'need' going around 'aten' is 'NEATENED'.
'but' acts as a link.
(Other definitions for neatened that I've seen before include "Put in order" , "Made tidy" , "Put to rights" , "put straight" , "Straightened or tidied" .)
