Hang prints in order to cover grub, oddly (6,2)
I believe the answer is:
string up
'hang' is the definition.
('string up' can be a synonym of 'hang')
'prints in order to cover grub oddly' is the wordplay.
'in order' indicates an anagram (the letters in a new order).
'to cover' means one lot of letters goes inside another.
'oddly' indicates alternate letters.
The alternating letters of 'grub' are 'gu'.
'prints' with letters rearranged gives 'strinp'.
'strinp' placed around 'gu' is 'STRING UP'.
(Other definitions for string up that I've seen before include "Carry out death sentence" , "Hang" .)
