Reluctance to move home? It’s overturned, in time (7)
I believe the answer is:
inertia
'reluctance to move' is the definition.
(I've seen this before)
'home? it's overturned in time' is the wordplay.
'home?' becomes 'in' ('he's home' can mean 'he's in').
'overturned' indicates an anagram.
'in' means one lot of letters goes inside another.
'time' becomes 'era' (an era is a period of time).
'it' is an anagram of 'ti'.
'ti' going into 'era' is 'ertia'.
'in'+'ertia'='INERTIA'
(Other definitions for inertia that I've seen before include "I tear in (anag.)" , "Tendency to do nothing or to remain unchanged" , "Unresponsiveness" , "Lack of movement" , "Lack of inclination to move" .)
