One way or another pig keeps untidy home (7)
I believe the answer is:
somehow
'one way or another' is the definition.
(I've seen this before)
'pig keeps untidy home' is the wordplay.
'pig' becomes 'sow' (I've seen this before).
'keeps' indicates putting letters inside.
'untidy' indicates an anagram.
'home' is an anagram of 'meho'.
'sow' enclosing 'meho' is 'SOMEHOW'.
(Other definitions for somehow that I've seen before include "For some unspecified reason" , "By unspecified means" , "By hook or by crook" , "For an unknown reason; so who, me? (anag.)" , "By one means or another" .)
