He's set the pages differently (6)
I believe the answer is:
sheets
'pages differently' is the definition.
Although both the answer and definition are verbs in their -s form, I don't see how one could define the other.
'he's set' is the wordplay.
'he's set' anagrams to 'SHEETS'.
However, I am not sure how the anagram is indicated.
'the' acts as a link.
Can you help me to learn more?
(Other definitions for sheets that I've seen before include "Bed covers" , "She set them on the bed" , "Pieces of paper or bedclothes" , "Bed coverings for the sailor's ropes" , "Bedclothes to be found on ships?" .)
