Inferior far too haphazard about last part of duties (2,1,4)
I believe the answer is:
of a sort
'inferior' is the definition.
(I've seen this before)
'far too haphazard about last part of duties' is the wordplay.
'haphazard' indicates anagramming the letters.
'about' is an insertion indicator.
'last part of' says to take the final letters.
The final letter of 'duties' is 's'.
'far'+'too'='fartoo'
'fartoo' with letters rearranged gives 'ofaort'.
'ofaort' going around 's' is 'OF A SORT'.
(Other definitions for of a sort that I've seen before include "Roughly" , "Rough, inexact, inferior" , "Vague, inexact" , "after a fashion" .)
