Lift thing he moved round back of house (8)
I believe the answer is:
heighten
'lift' is the definition.
(heightening is a kind of lifting)
'thing he moved round back of house' is the wordplay.
'moved' is an anagram indicator.
'round' is an insertion indicator.
'back of' says to take the final letters.
The last letter of 'house' is 'e'.
'thing'+'he'='thinghe'
'thinghe' is an anagram of 'highten'.
'highten' going around 'e' is 'HEIGHTEN'.
(Other definitions for heighten that I've seen before include "Lift" , "Make more intense, say awareness" , "Move up" , "Intensify; make taller" , "Raise" .)
