Mope around composing verse (4)
I believe the answer is:
poem
'composing verse' is the definition.
'poem' can be an answer for 'verse' (I've seen this before). I'm not sure about the 'composing' bit.
'mope around' is the wordplay.
'around' is an anagram indicator.
'mope' with letters rearranged gives 'POEM'.
Can you help me to learn more?
(Other definitions for poem that I've seen before include "Rhyme" , "Piece of verse" , "Literary composition, sometimes in verse" , "Mope about in verse" , "Ode" .)
