The Sun, say, apparently unable to move father's home? (8)
I believe the answer is:
vicarage
'home?' is the definition.
(vicarage is a kind of home)
'the sun say apparently unable to move father's' is the wordplay.
I cannot really understand how this works, but
'sun' could be 'ra' (ancient Egyptian sun god) and 'ra' is found within the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for vicarage that I've seen before include "cleric's place" , "6's residence" , "Clergyman's residence" , "House of a member of the clergy" , "Priest's residence" .)
