Beginning to fix home after end of tornado (6)
I believe the answer is:
origin
'beginning' is the definition.
(origin is a kind of beginning)
'fix home after end of tornado' is the wordplay.
'fix' becomes 'rig' (rigging is a kind of fixing**).
'home' becomes 'in' ('he's home' can mean 'he's in').
'after' means one lot of letters go next to another.
'end of' says to take the final letters.
The last letter of 'tornado' is 'o'.
'rig'+'in'='rigin'
'rigin' after 'o' is 'ORIGIN'.
'to' is the link.
(Other definitions for origin that I've seen before include "Place or point of beginning (6)" , "spring" , "Beginning, starting point" , "Place where something begins" , "Point of creation" .)
