Draft review of shambolic nephew's housing (6)
I believe the answer is:
pencil
'draft' is the definition.
(thesaurus)
'review of shambolic nephew's housing' is the wordplay.
'review of' is a reversal indicator.
'housing' says the answer is hidden in the clue (part of the clue houses the answer).
'licnep' is hidden within 'shambolic nephews'.
'licnep' backwards is 'PENCIL'.
(Other definitions for pencil that I've seen before include "__-sharpener" , "One doing boring clerical work?" , "Drawer with graphite in" , "writing equipment" , "Graphite stick" .)
