To a degree is upsetting and does wreck homes (6)
I believe the answer is:
abodes
'homes' is the definition.
('abode' can be a synonym of 'home')
'to a degree is upsetting and does wreck' is the wordplay.
'to a degree' becomes 'ba' (BA is an example).
'is upsetting' shows that the letters should be reversed in order.
'and' says to put letters next to each other.
'wreck' indicates anagramming the letters.
'ba' reversed gives 'ab'.
'does' with letters rearranged gives 'odes'.
'ab'+'odes'='ABODES'
(Other definitions for abodes that I've seen before include "Dwelling places" , "Places of residence" , "Houses, homes" , "Dwelling-places" , "Places where people live" .)
