Messy home embraced by pig, in a way (7)
I believe the answer is:
somehow
'in a way' is the definition.
(I've seen this before)
'messy home embraced by pig' is the wordplay.
'messy' is an anagram indicator.
'embraced by' means one lot of letters goes inside another.
'pig' becomes 'sow' (I've seen this in another clue).
'home' anagrammed gives 'meho'.
'meho' placed within 'sow' is 'SOMEHOW'.
(Other definitions for somehow that I've seen before include "By hook or by crook" , "In an unspecified way" , "One way or another" , "By one means or another" , "For some unspecified reason" .)
